Learning statement
At the beginning of this semester, I felt uncertain and overwhelmed, adjusting to a new environment and a new academic culture. Coming from France, where I just got out of high school, I found myself thrown into an entirely different system with expectations I had never encountered. For instance, I had never worked on assignments in English or experienced grading as it is done in the United States. This transition was initially confusing, and I spent hours working on my first assignments, unsure of what my professors were really looking for.
However, as the weeks went by, I began to understand what was expected of me, not just in terms of academic performance but also in terms of personal discipline. In particular, I gained a deeper appreciation for organizational skills. Unlike high school, where you are constantly moving from one class to another, the university schedule left me with more free time. This flexibility, while a welcome break, also required me to take charge of my time and learning. I realized quickly that if I didn’t plan my study schedule carefully, I risked falling behind. As a result, I developed a kind of a routine that helped me stay on track.
One of the most significant things I’ve learned this semester is how to conduct proper academic research and cite sources accurately. In France, citation and academic integrity were not emphasized the way they are here, and at first, I felt completely lost. But over time, I became more comfortable with academic writing conventions, particularly with the process of citing correctly and using sources responsibly. This was not only a technical skill but also an ethical one, as I began to understand the importance of crediting others’ work.
Group projects, particularly our case studies, also played a significant role in my learning. These projects required collaboration, critical thinking, and the ability to integrate diverse resources and viewpoints. I found myself searching for information not only from course materials but also from external sources, improving my research skills and expanding my knowledge beyond the textbook. Additionally, working in groups helped me see how different perspectives can contribute to problem-solving and decision-making. These experiences have encouraged me to approach problems from multiple angles and think critically, rather than accepting information at face value.
Another important learning experience this semester has been understanding my own preferences and strengths as a learner. I discovered that I perform best when I can separate tasks based on the level of concentration required. For example, I found that I needed quiet, uninterrupted time to write research papers and work through complex problems. On the other hand, I could use more social environments for tasks that were more creative or involved reviewing materials, such as preparing slides for presentations. This has helped me optimize my productivity and manage my study sessions in a way that aligns with my learning style.
Therefore, I hope to find even more key points about my learning preferences during next semester to continue optimizing my learning approach.
Common Reading
As Martin Luther King Junior said once, You don’t have to see the whole staircase. Just take the first step.
I’ve always dreamt about coming to the U.S one day. I don’t really remember why at the beginning, but it has been years that I was looking for a way to finally get here. When you dream it, it looks beautiful. When you start to work for it, you find it hard, but you still have this beautiful dream in your mind. When you finally get it, you feel like it’s the best day of your life. But when you arrive, you start to see this dream in another way. It relates easily to Fisher’s experience when he mentions his hard time at college working to enter Med School : “I struggled and soared over those four years, in the process building a record sufficient to earn admission to medical school.” page 45. The day I left my hometown, I was sitting in the plane, and the only thing I was thinking about was: I wish it was only holidays, I wish I could return home after a week. The plane didn’t start that I already wanted to get back to my house. I wasn’t sure anymore of what I really wanted, cause when it’s far, you don’t realize. The whole year, my friends were asking me: aren’t you scared of going so far, by yourself, living in a new country without knowing anybody? However, the only feeling I had was excitement.
Nevertheless, while I was taking my flight, I was completely freaking out. How was I supposed to leave my old life behind and start a new one just like that? It’s so hard to make friends when you don’t know anybody, how are you supposed to live normally when all your loved ones are on the other side of the globe?
I think it’s the first time I really had a conscience of what I was about to do. During the whole flight, I authorized myself to cry and to think about what I was going to give up on. Later, when we arrived in Chicago, I was scared, scared of the city, which was huge, and was making me so small compared to it, like I thought that I was going to fall under the buildings and the skyscrapers. During the whole morning visiting Chicago, I had like a big hole in my stomach, the fear was like flowing in all my veins and sometimes I even had trouble breathing. When Dr. Fisher describes his patients having trouble breathing, it reminds me of me, and the fear that was growing inside of me. I couldn’t stop thinking about how the United States would eat me so fast.
But then, my mom came and said to me just one sentence that helped me so well, as I was regretting my old life without having even started the new one. She told me: It’s better to go, and cry because you leave your loved ones, than leaving without having any attachment behind. Because you’ll always know that you have a home to come back to. By this sentence, I just got better in a second, of course, all my fears didn’t just disappear, however, I was feeling much better, because I knew that when the time to come home would arrive, my friends and my family would be proud of what I did. This was like my quote for everyday when I would feel a little bad, or sad. That’s why, when I arrived at college, I didn’t even turn back. As Fisher says on page 44 “I did not look back when I stepped out of my parents’ minivan at college.”.However, college life is still challenging sometimes.
The first days are always the worst; you don’t really know anybody, you feel completely lost, and don’t want to make a bad impression in front of others. My first reflex was to close myself off from the others. But I somehow quickly understood that this is not a solution, especially when you are from another country. If you don’t open up to others, they won’t come to you. The fact is, the beginning looks impossible, then, you piece by piece kind of find your way. I think we get used to everything and no matter the hard side of it, we still find a solution.
In summary, the resilience shown by Dr. Fisher and his patients helps me understand that even in overwhelming circumstances, facing fears and taking small steps forward can lead to overcoming challenges. By embracing my fears and opening up to new experiences, I can gradually build my life at Illinois College, finding strength and support along the way.
As I said, the beginning of this adventure was really stressful. But even if I didn’t properly show it to the people around me, I found some support helping me deal with that. As Dr. Fisher says, yes, friends and family provide emotional support. Sometimes, even a random person you talk with for a few minutes can help you deal with some negative emotions you are having at that moment. I found myself being calmer right after just talking a few minutes with someone about our schedules or our hometown.
I think that to succeed, you have to drop every negative emotion or feeling that could obscure your path. No matter how deep this emotion is, you have to let it go. Sometimes by talking about something else, or sometimes by asking for help, or just by asking someone if they can listen to you. For the moment, I haven’t experienced the real homesick moment we all get one day. I just felt a little bit sad some days, but I made some friends here who are living something similar to me right now, which helps me get through the hard times.
I think that to build strong connections with others, you have to be honest. You can’t be a person you aren’t. Sometimes you want to feel like you are a part of something, but if these people don’t match you, this isn’t going to work. You can’t build connections with people who don’t know who you are. Dr. Fisher, while working, needs people who understand how stressful it is to work in this environment. At the same time, he also needs people who can help him escape his usual stressful environment. That’s how we live our college experience. It’s good to share our own experiences with other students, to share how we each deal with being far from home and with the classes. But it’s also important to have a person who you can talk to, just to take a deep breath of fresh air.
Personally, my family and my friends back in France help me escape sometimes from the reality I’m living here, and they make me talk about all the things that happen here. When I talk to them, I feel grateful for being here. While talking with my new friends here makes me realize that, yes, we have to work hard, but the price is worth it.
However, talking with these people helps me particularly because they really see and know me.
To be seen is really important sometimes, and it doesn’t always have the same meaning; it depends on the environment. On page 25, we can distinguish a particular passage : ‘She’s been seen by a heart specialist. But do I really see them ?”. As Dr. Fisher explains, patients need to be seen not just for their injuries or illnesses but as real human beings, not just the problem they are suffering from. When you go to the hospital, you’re not just dealing with physical pain but also emotional distress. Patients need someone to listen to their stories and offer support. Sometimes, what they need most is not just a doctor but someone who listens and reassures them that everything will be okay.
To be seen, in any relationship, means that the other person recognizes more than just your physical appearance or what you share outwardly. It’s about understanding your background and how you handle your life. I didn’t always see the importance of being seen in a global way when I was at home because I knew I could return home at the end of the day. However, being away from home makes it much harder, and being seen by the people around you can be incredibly helpful. Whether it’s with grades, courses, or personal issues, if people don’t really know who you are, it’s harder to get effective help. For example, if a professor knows that failing a test isn’t typical for you, they might offer more support. But if they don’t know you, they might just assume you don’t care.
At the start of college, people don’t know each other well, so it’s common to make assumptions based on initial impressions. By making an effort to truly understand and see each other, rather than judging based on appearances, you can form deeper, more meaningful connections. This helps transition from high school to college and makes navigating new experiences a bit easier.
As I think about my future at Illinois College, the lessons from The Emergency can guide me in setting goals and staying motivated. Dr. Fisher learned that everything he did was for something much bigger than himself. While I might not want to work in medical assistance due to a fear of seeing people suffer, I recognize that there are many ways to help the world. For example, working in environmental conservation can greatly benefit the planet and address international issues.
The book shows that even if you pursue something you’re passionate about, you may still face hard choices and realize that your dream job might not be as perfect as you imagined. You’ll need to make decisions and deal with the consequences because that’s how the world works. The Emergency also highlights that inequities—racial, religious, and gender—persist even in 2024. I don’t want to sit idly by; instead, I feel a strong urge to contribute to the community and address these issues.
Academically, my goal should be to always strive for improvement. It’s not just about grades or skills but about how what you learn can impact others. This ties into the butterfly effect—the idea that a small action can have a significant global impact. My college experience can provide knowledge and tools to help me make a difference in the future. A good professor can inspire me to discover a passion and set meaningful goals. My time at college is an opportunity to gain insights and develop skills that can help me contribute positively to the world, and continue to reach my goals.
Element research paper
First draft
TITANIUM (history)
The Titanium element was first discovered in 1791. The mineralist and geologist Rev. William Gregor found an interesting mixture of magnetite, iron oxide, and a new metal. However, it was only four years later that Martin Heinrich Klaproth, a German scientist, was studying the components of an ore and realized that it had a new metal in it, and named it Titanium. Later, they connected with the component found in the sample of Gregor’s experiment.
Its name comes from Greek mythology, “Titan”, as the titans, were extremely strong and resilient.
TITANIUM (what is it ?)
Titanium is a common element found in the Earth’s crust. Two primary minerals that contain titanium are Rutile and ilmenite, which make up 24% of the Earth’s crust. Therefore, Titanium is one of the ten most abundant Earth metals and can usually be found in rocks and sediments.
Titanium, with its 22 protons, is a transition metal, which indicates that it can bond using electrons from multiple energy levels. The metal is silver in color, and it has a low density, which is about 60% the density of iron, however, it has a high strength, and it’s also resistant to water corrosion, which contributes to longer product lifespans, it often do not require additional coatings, reducing the use of potentially harmful chemicals and extending the life of the products (C. D. et al., 202). A study by D. A. D. A. J. M. et al. (2017) highlights how the longevity of titanium products reduces the need for frequent replacements, leading to lower overall resource consumption over time. The material can be ductile in an oxygen-free environment. Nevertheless, magnesium and aluminum allow oxidation immediately upon exposure to air.
TITANIUM (properties)
Titanium has unique properties that can make it highly sought in many modern and innovative applications. It’s strong but also light, it has an atomic mass of 47.9gm. The tensile strength of titanium is between 30,000 psi to 200,000 psi depending on the type of Titanium. Its light density combined with its tensile strength reduces the load and strain of heavier metals, which will reduce the overall weight of the objects when it’s used in manufacturing. Titanium has the highest strength-to-density ratio of any metallic element. It has a high melting point, therefore, titanium is usually used in airplanes, missiles, and rockets, where strength and high-temperature resistance are really important.
Thanks to its properties, titanium is one of the most biocompatible metals, which is why it’s highly used in medical applications, such as cardiac valves and surgical implantable devices.
Titanium is highly recyclable, studies show that 95% of titanium can be recycled without significant loss of properties. Research by R. A. H. et al. (2020) emphasizes the energy savings and reduced carbon footprint associated with recycling titanium compared to primary extraction.
While the extraction of Titanium can be really energy-intensive, several advancements in extraction technologies can improve its sustainability. For example, the use of newer methods like the Kroll process and modifications to existing methods can minimize environmental impacts (M. T. et al., 2021).
What does sustainable mean? (general)
Sustainable technologies refer to methods, practices, and materials that minimize environmental impact. It can also enhance resource efficiency, and support ecological balance. These technologies are used to meet current needs, however, they do not compromise the ability of future generations to meet their own needs. They are concentrated on renewable resources, energy sufficiency, waste reduction, and product lifespan.
Materials are really important in sustainability, there are many reasons that explain it. First, how materials are chosen impacts resource consumption, the use of energy, and waste generation during the product lifespan. However, it also has environmental impacts, from greenhouse gas emissions to habitat destruction and pollution. The use but also extraction of these materials affect the environment.
Their way of being recycled if it’s possible, could help reduce waste and could help to conserve natural resources.
Finally, if a material does not have to be replaced continually, helps avoid the frequency of consumption and waste.
Titanium sustainable?
We can therefore ask, how Titanium could enter in this case of sustainable material.
As we have seen before, it’s actually all its properties that make it a sustainable material.
First, Titanium has a high strength and corrosion resistance resulting in longer-lasting products.
On the same idea, while it has to be recycled, Titanium does not lose a lot of quality, even if it’s recycled several times. This makes it an efficient choice for reducing waste.
Titanium, either by its extraction and processing technologies, has been subject to many advances that enable it to be way less energy-intensive, and more environmentally friendly.
It promotes sustainability and avoids waste also in the healthcare sector because it reduces the need for repeated procedures and devices.
Why is this research important? The main goal is to investigate titanium’s sustainability, which will help identify the different ways to improve material choices in various industries, and will therefore be aware of more eco-friendly practices and innovations.
Important questions that we could ask are :
- What are the life cycle environmental impacts of titanium compared to other materials?
- How can the recycling processes for titanium be optimized to enhance sustainability?
- What innovations in titanium extraction and processing can further reduce its environmental footprint?
- In what specific applications does titanium provide the greatest sustainability benefits?
- How do consumer perceptions of sustainability influence the adoption of titanium in various markets?
TITANIUM NITRIDE METAMATERIALS: ENHANCING SOLAR ENERGY ABSORPTION
The study by Zhang et al. (2023) on titanium nitride metamaterials introduces innovative mechanisms for improving solar energy absorption, specifically targeting the capture of invisible ultraviolet (UV) light while ensuring transparency to visible light. This research highlights the unique capabilities of metamaterials, potentially transforming conventional solar energy technologies.
Central to this investigation is the meticulous design of titanium nitride metamaterials, which incorporate engineered microstructures that facilitate the absorption of UV light through resonant modes. By manipulating the material at scales smaller than the wavelength of light, the researchers have crafted a system capable of efficiently harnessing energy from wavelengths often ignored by standard solar panels. This selective absorption leverages chirality and tailored surface features, allowing the metamaterials to focus specifically on UV radiation.
Importantly, this design ensures that while UV light is effectively absorbed, the visible spectrum remains transparent. The material’s properties are finely tuned to resonate with UV wavelengths without absorbing longer wavelengths. This selective absorption not only maximizes energy capture but also permits the unobstructed passage of visible light, which is crucial for preserving the aesthetic appeal of solar panels.
The potential applications of titanium nitride metamaterials in solar panels are significant. By integrating these advanced materials, manufacturers could markedly enhance the overall efficiency of solar energy conversion, as the ability to capture UV light introduces an additional energy source that traditional panels overlook. Additionally, the inherent durability and resistance of titanium nitride to environmental degradation make it a suitable choice for outdoor solar applications, promoting longevity and reliability.
Beyond solar panels, the implications of this research extend to other fields, including photodetectors, sensors, and various optical devices where selective light absorption is beneficial. The incorporation of these metamaterials could lead to the creation of more visually appealing solar panel designs that adapt seamlessly to diverse surfaces, such as building-integrated photovoltaics. In conclusion, the findings of Zhang et al. pave the way for advanced solar technology and broader applications in optical devices, signaling a new era of energy-efficient solutions.
Titanium in battery technologies: ENHANCING SOLAR ENERGY ABSORPTION
Lithium titanium oxide anodes are really recognized as a potential alternative in lithium-ion battery technologies, particularly for electric vehicles. As highlighted by Han et al. (2014), these anodes give several advantages that could improve both performance and durability. It for example has an exceptional cycle life, lithium titanium oxide can often endure over 10,000 charge and discharge cycles with minimal capacity degradation. This remarkable longevity contributes to enhanced battery lifespans, reduced need for frequent replacements and thereby lowered the overall cost of ownership for electric vehicles.
In addition to their durability, these anodes are known for their high efficiency. The stable crystal structure of this material helps maintain consistent performance throughout its life cycle, which is crucial for ensuring reliable energy delivery in electric vehicles. Moreover, the porous form of titanium dioxide utilized in these anodes enhances conductivity without requiring the additional conductive additives commonly used in conventional battery electrodes. This not only streamlines the manufacturing process but also decreases the weight of the battery, which is a vital consideration in vehicle design.
Another essential advantage is the safety of lithium oxide. The material significantly reduces the risks of lithium plating during fast charging, which can lead to thermal runaway major safety concern in lithium-ion batteries. By mitigating this risk, lithium titanium oxide enhances the safety of electric vehicles. Moreover, the unique properties of the anode allow rapid transport, which can lead to quicker charging time, which matches the consumers’ demands.
In addition, lithium titanium oxide shows high performance across different temperature ranges, which maintains its efficiency even in challenging conditions. The resilience adds variety and versatility to electric vehicles, which makes them suitable for diverse climates and operating conditions.
In summary, lithium titanium battery anodes in electric vehicles can not only improve performance and durability but also align with the sustainable goals fixed. The combination of this extended cycle life, high safety standards, and enhanced charging capacities positions lithium titanium oxide as a key player in the future of battery technology, driving advancements in electric vehicle accessibility.
Titanium in Environmental Protection Technologies
Titanium dioxide is a super cool and really effective photocatalyst that helps with things like cleaning water and improving air quality. What makes titanium so good at breaking down nasty stuff when exposed to ultraviolet light is its unique properties. When it gets hit by UV light, it produces these reactive oxygen species—think hydroxyl radicals and superoxide ions—which kick off oxidation reactions that turn harmful substances into harmless stuff like carbon dioxide and water.
In water purification, titanium dioxide works wonders on different types of water. For drinking water, it can get rid of dangerous contaminants like pesticides, pharmaceuticals, and microorganisms, making sure the water is safe to drink. In wastewater treatment, it’s essential for breaking down toxic organic pollutants from factories, which really helps lessen the pollution put into the environment. It even plays a part in cleaning up rivers and lakes, helping restore aquatic ecosystems. Groundwater cleanup is another area where titanium shines, tackling various types of water contamination.
One of the coolest things about titanium is that it’s insoluble in water. This means it won’t leach into the water that’s being cleaned, allowing treatment systems to work continuously. Plus, it’s tough against most chemicals, so its photocatalytic properties stick around over time, making it a cost-effective option for long-term environmental cleanup.
Besides cleaning water, titanium dioxide also helps enhance air quality. It’s used in a bunch of applications like coatings, building materials, and filtration systems. In these cases, it oxidizes organic compounds and pollutants, which helps reduce indoor air pollution and improves the air we breathe overall.
In short, titanium dioxide is a key player in environmental applications, offering effective and sustainable ways to purify water and clean the air. Its ability to break down different pollutants, combined with its stability and chemical resistance, makes it super important for fighting pollution and promoting a healthier environment.
Cost and Availability of Titanium
Titanium is often praised for being super strong for its weight and for not rusting easily, but it comes with some pretty big challenges, especially when it comes to cost and availability. Even though titanium is more common in the Earth’s crust compared to other metals, getting it out is a different story. It mostly shows up in minerals like rutile and ilmenite, which aren’t very concentrated and need a lot of work to extract the titanium. The main way to do this is the Kroll process, where titanium tetrachloride (TiCl₄) is reduced with magnesium at really high temperatures. This method uses a ton of energy and requires advanced setups, which really hikes up the costs of making titanium.
Because of this, making titanium is way more expensive than using materials like aluminum or steel. This price difference comes from several things—including how mining works, the energy needed for the extraction process, and the tech investments needed for making titanium alloys. So, while titanium is great for specific high-performance uses like aerospace, automotive, and medical devices, its cost can hold it back in industries that have tighter budgets. Plus, the titanium market can be pretty unstable. Changes in global demand and supply can send prices soaring or crashing, making it tough for manufacturers who depend on titanium to keep their businesses steady.
- Environmental Impact of Titanium Extraction and Processing
The extraction and processing of titanium raise some serious environmental issues that we really need to think about. The mining often uses strip mining or open-pit methods, which tear away vegetation and topsoil. This not only causes soil erosion but also leads to more sediment getting into nearby water bodies, which can mess with soil fertility. Over time, losing topsoil can make land useless for farming, putting local food security and people’s jobs at risk.
On top of that, processing titanium involves a bunch of chemicals that can leak into groundwater or surface water, causing contamination. Heavy metals and other pollutants released during extraction and refining can harm local communities and lead to long-term damage to ecosystems, especially affecting fish and other aquatic life. Plus, the physical space taken up by mining can destroy habitats, particularly in sensitive areas. Disrupting local plants and animals can hurt biodiversity since many species rely on stable habitats to thrive.
Also, the energy needed to extract and process titanium is pretty high, usually depending on fossil fuels, which contribute to greenhouse gas emissions. As companies start to focus more on sustainability, this high energy use can be a big challenge for them to reduce their environmental impact. Thankfully, there’s a growing movement towards sustainable mining practices. People are looking into better extraction methods, reducing waste, and reclaiming land to lessen the damage done to our planet.
“While these practices can definitely help the environment, they also come with their own challenges and costs. So, companies really need to find a way to balance taking care of the planet while still making a profit.
In the end, titanium has a lot going for it when it comes to performance and durability. But the issues around its cost, how easy it is to get, and its impact on the environment can be pretty tough to deal with. To tackle these problems, it’s super important for everyone—from businesses to government and communities—to work together and come up with sustainable solutions. This way, we can make titanium a better choice for more uses.”
Conclusion
In this paper, we explored the different properties of titanium, from its discovery, to its characteristics, and significant role in diverse applications. Titanium’s unique combination of strength, lightweight, and corrosion resistance, makes it a really useful and full potential for industries, in various fields. The fact that titanium is recyclable, makes it a really sustainable material, which contributes to reducing environmental impact and pollution.
In addition to the fact that it’s a recyclable compound, titanium aligns with the principles of efficiency and sustainability, because of its durability and longevity.
Future studies could focus on enhancing again its recyclability, but also by developing more sustainable extraction methods. By investing in this research, we can harness titanium’s capabilities to meet the challenges of tomorrow while preserving our planet for future generations.

Convocation reflections
Today at the convocation, I learned more about the U.S. election system, which I won’t be able to experience firsthand. The decentralized nature of the system makes it challenging to understand how elections unfold. The professor explained the various administrative roles involved in conducting polls and ensuring the accuracy of votes. For smaller elections, recounts are sometimes conducted to guarantee that everything is correct.We also discussed the media’s projections. Although they usually wait until they are fairly certain before announcing results, sometimes these projections can be misleading. As the professor emphasized, it’s better to be accurate than to be fast. I obviously can’t vote in this country since you must be at least 18 years old, a U.S. citizen, and meet your state’s residency requirements. But the convocation was meant to highlight why voting is important, however we only touched on it briefly. Personally, I believe voting is crucial, even if you don’t feel aligned with any candidates. Casting a blank vote is still a valid expression of your opinion. It highlights that no candidate reflects your values or ideas, and this can be a powerful statement. Ultimately, voting is vital for shaping a better world. It allows us to express our needs and express what is best for the entire population. By participating in elections, we contribute to ensuring that representatives truly reflect the voices of the people.
Today, we had a convocation about consent, and I found it incredibly important given the current issues surrounding it, especially in college settings. This topic resonates with me personally, as it’s something my mom often worries about. During the discussion, we addressed the fear that many people have about intervening in situations where consent may be unclear. I’ve heard numerous stories of aggression in public places where bystanders hesitated to act, thinking that someone else would step in. By openly talking about these barriers, we help people realize that inaction can have serious consequences. It’s essential to emphasize that taking action doesn’t always require a dramatic response. Sometimes, simply distracting someone or changing the subject can diffuse a tense situation. It’s often easier than we think to find a way to intervene positively. Additionally, we need to talk about consent and respectful behaviors within our friend groups. Confronting friends about their actions can be challenging, but if we don’t speak up, who will? Allowing harmful behavior to go unchecked can lead to more serious issues down the line. In conclusion, it’s crucial for us all to be proactive in discussing consent and supporting each other in creating a safe environment. Small actions can lead to significant change, and we all have a role to play.
Witnessed Chemical Demonstration/Activity Reflection
In the experiment with fluorine, it’s observed the reactivity of fluorine gas in the presence of another substance. Fluorine is highly reactive and can react violently with many elements, even at room temperature. A common demonstration with fluorine involves its reaction with hydrogen.
Fluorine’s high reactivity: Fluorine is the most electronegative element, meaning it has a strong tendency to attract electrons from other atoms. This makes it highly reactive, especially with hydrogen and metals.
Exothermic reactions: The reaction between fluorine and hydrogen releases a lot of energy in the form of light and heat, demonstrating the power of fluorine’s bond-forming ability.
For magnesium, the demonstration involved burning magnesium ribbon in the air. When magnesium is heated, it burns with a bright white flame and produces magnesium oxide (MgO) as the product.
Magnesium’s reactivity: Magnesium is a highly reactive metal, especially when heated. In the presence of oxygen, it burns with intense heat and light. This is due to its low ionization energy, which makes it easy for magnesium atoms to lose electrons and form positive ions.
Formation of magnesium oxide (MgO): The reaction between magnesium and oxygen leads to the formation of magnesium oxide, a white powder. This demonstrates the oxidation process where magnesium loses electrons to oxygen (which gains electrons), forming an ionic compound.

Motivation for service I’m deeply motivated to engage in service activities for several reasons. First of all, I think it is quite a duty to help the people in need. For example, during a local food drive, I felt a profound sense of responsibility as I helped sort and distribute food to those who needed it most. No matter if you have money or not, you can just help by proposing your services, or being physically present to help raise food pantries or other types of projects. However, I think that everything is not only determined by helping people but also the environment. I’ve participated in clean-up drives where we removed litter from local parks, and this experience reinforced my belief that we are all living on the same planet, therefore if any of us could just do a few gestures, it would make a huge difference in the environment’s well-being. Nevertheless, it’s not only a duty. For my part, I’ve already done volunteering, and found the experience relatively exciting and enriching. It made me realize the joy of giving without expecting anything in return. The feeling of not doing something for you, but only for someone else. I cannot really describe it, it makes you feel good, and less selfish. Types of services I think the ones that match better with me are the ones concerning the environment and also the ones about community service. I would like to be involved in projects like tree planting and local environmental advocacy. Doing projects about how to improve the environment and also how to preserve it resonates deeply with me. How to enhance its protection and how to limit pollution are issues I am passionate about. However, it’s not the only field I would like to work on. I would also like to make projects about fundraising to help children to go to school and help families to pay for their children’s illnesses. Back in my hometown, I have an association working to help families pay for specific intervention concerning rare or orphan diseases. Participating in fundraisers and awareness campaigns for this cause has been incredibly fulfilling. Complexity of service So obviously, service works exactly the same as when you want to help someone. If this person doesn’t want your help, sometimes, forcing it can be worse than just keeping going. You have to be sure that the people are aware and agreeing on what you are about to do. For example, in one project, we had to ensure that the community members were fully informed and consenting before proceeding with our initiatives. It’s still their choice to be helped or not. Whether they decide to or not, you have to respect their choice. Sometimes, you can’t force people to accept something, especially in these conditions. Sometimes, if people are offered some help, it makes them realize their condition, and they may not accept it. Sometimes, people just think that they can get out of it by themselves. Personal takeaways I think I’m going to continue investing myself in community services, both here and in France. Because it provides a sense of pride that nothing else can procure me. Whenever I won a championship or did an amazing concert, it is not the same thing. It’s completely different because it never has to deal with you. It’s all about the others. This unique sense of satisfaction and pride from helping others is something I want to keep experiencing and fostering in my future projects.

This past Saturday, September 21st, I had my community service at the Oktoberfest festival in Jacksonville. It was organized by the Rotary club for fundraising. It’s an event centered around German culture, where people gather to enjoy traditional food and drinks. My main job was selling T-shirts, even if the rain decorated the instant. When I arrived, we started unpacking the T-shirts and folding them on tables. Just when we thought we were all set up, the rain came pouring down. We quickly had to move everything under a bigger tent to keep the items dry. It was a bit chaotic, but it just reminded me of how important it is to adapt and work together in unexpected situations. Once we got everything sorted, I was selling shirts and candies. Even though it wasn’t crowded as I hoped, it was still great to see people dressed in traditional German outfits, really getting into the vibe of the festival. I noticed that even during quieter moments, when we were just waiting for customers, there was a sense of community. The people attending were genuinely friendly and they were appreciating our efforts. I interacted with a lot of different people throughout the day. These interactions really highlighted the importance of teamwork and inclusivity. Everyone was there for the same reason, to create a fun atmosphere and support our community. It was clear that every person’s role, big or small, was valuable. This kind of collaboration reflects the values at IC, where building relationships and understanding different viewpoints are essential. What I learned about myself during this experience was pretty good. I discovered that I could be patient and adaptable when things don’t go as planned. Initially, I expected a busier day, but I found joy in the slower moments, just enjoying people being happy being there. This experience reinforced the idea that community service isn’t just getting things done, it’s about building relationships and being there for each other. As I think about my time at Illinois College, I realize that this experience will help shape my approach as a student. It highlighted the importance of being actively involved in campus life and connecting with diverse groups of people. The teamwork I practiced will be essential for group projects in my classes and in making the most of my relationships on campus. By trying to do more services and community service, I can enhance my college experience and contribute positively to the IC community. Looking ahead, I’m committed to taking these lessons with me. I plan to keep volunteering and finding ways to connect with others while making a difference. Living out the values of Illinois College means actively engaging with my community and respecting different perspectives. I’m excited to carry these principles into my future. In conclusion, volunteering at Oktoberfest was more than just selling T-shirts; it was a chance to connect with others, learn about teamwork, and grow as a person. I’m looking forward to applying what I learned throughout my time at Illinois College and beyond, continuing to foster a sense of belonging and support in everything I do.
Service Reflection
At the beginning of this semester, I felt uncertain and overwhelmed, adjusting to a new environment and a new academic culture. Coming from France, where I just got out of high school, I found myself thrown into an entirely different system with expectations I had never encountered. For instance, I had never worked on assignments in English or experienced grading as it is done in the United States. This transition was initially confusing, and I spent hours working on my first assignments, unsure of what my professors were really looking for.
However, as the weeks went by, I began to understand what was expected of me, not just in terms of academic performance but also in terms of personal discipline. In particular, I gained a deeper appreciation for organizational skills. Unlike high school, where you are constantly moving from one class to another, the university schedule left me with more free time. This flexibility, while a welcome break, also required me to take charge of my time and learning. I realized quickly that if I didn’t plan my study schedule carefully, I risked falling behind. As a result, I developed a kind of a routine that helped me stay on track.
One of the most significant things I’ve learned this semester is how to conduct proper academic research and cite sources accurately. In France, citation and academic integrity were not emphasized the way they are here, and at first, I felt completely lost. But over time, I became more comfortable with academic writing conventions, particularly with the process of citing correctly and using sources responsibly. This was not only a technical skill but also an ethical one, as I began to understand the importance of crediting others’ work.
Group projects, particularly our case studies, also played a significant role in my learning. These projects required collaboration, critical thinking, and the ability to integrate diverse resources and viewpoints. I found myself searching for information not only from course materials but also from external sources, improving my research skills and expanding my knowledge beyond the textbook. Additionally, working in groups helped me see how different perspectives can contribute to problem-solving and decision-making. These experiences have encouraged me to approach problems from multiple angles and think critically, rather than accepting information at face value.
Another important learning experience this semester has been understanding my own preferences and strengths as a learner. I discovered that I perform best when I can separate tasks based on the level of concentration required. For example, I found that I needed quiet, uninterrupted time to write research papers and work through complex problems. On the other hand, I could use more social environments for tasks that were more creative or involved reviewing materials, such as preparing slides for presentations. This has helped me optimize my productivity and manage my study sessions in a way that aligns with my learning style.
Therefore, I hope to find even more key points about my learning preferences during next semester to continue optimizing my learning approach.

Workshop learning
Workshop about identity :
Reflecting on the workshop about identity, privilege, and power, it’s clear how these issues relate to the core values of Illinois College as a liberal arts institution. Illinois College is committed to fostering an environment where all members of the college community can find support for their individual growth, regardless of race, ethnicity, gender, sexual orientation, age, disability, religion, national origin, language use, socioeconomic status, first-generation status, veteran status, or political ideology. The workshop addressed how society often ranks individuals based on characteristics such as race, gender, and sexual orientation, leading to the exclusion of some people from basic human rights. In contrast, Illinois College works hard to create a safe and inclusive environment for everyone.
For example, one of the first sessions during Welcome Week focused on building a Sense of Belonging, encouraging us to support each other and integrate into the college community regardless of our differences in appearance, background, or beliefs. This commitment to inclusion aligns with my personal goals. I want to contribute to maintaining this sense of belonging and inclusion within the college and beyond. I believe that no one should feel inferior because of their nationality, religion, skin color, gender, or body type. Everyone’s voice is important, and we must reject discrimination based on these external characteristics. People are much more than the categories society places them into.
During my time at Illinois College, I am determined to be open-minded and engage with people from diverse backgrounds and experiences. By embodying these values, I hope to help foster a vibrant and inclusive community at the college and apply these principles in my life outside of school as well. In my future career, I am committed to working in environments where women are not treated as inferior and where equality is truly valued. I refuse to be part of any company that does not respect and values women equally as men. Just as Illinois College fosters an environment of respect and equality, I will seek to uphold these principles in my professional life. These values will guide me as I navigate my career, ensuring that I contribute to workplaces where everyone is treated fairly and with dignity.
Workshop about test taking and reading :
During yesterday’s workshop, I found out that my study methods aren’t that bad, and that I can change some details to make my lectures stick to my long-term memory more than just for the time of the test.
First, they showed us that multitasking is not always the best idea to study, foremost because it makes you spend more time on your subject when you could do smaller tasks faster. Moreover, I was reassured that it’s not only me who needs a deafening environment to work better. Sometimes people tell me that I’m insane working with very loud music, or in a gym. But by doing their survey, I found out that the best environment, where at least I have the better concentration, is the gym. Because, first, most of the time when I go there, even if people are playing on the courts, I work alone or only with a few friends. Therefore, I’m more focused on my homework, and nobody distracts me from my tasks. On the other hand, when I study in the writing center at Lincoln, I’m always surrounded by a lot of people, and I always end up talking more than learning.
Concerning the tests, I don’t really have test anxiety. I’m more excited to take a test than stressed because it allows me to test and challenge myself. But in the other subjects, it permitted me to adjust some details which might be really helpful for my studying method.
Workshop about citation and database :
Today’s workshop was useful because I’m not really used to using particular citations or even citing sources well. Therefore, I gained valuable information and helped with different citation styles, such as ACS and MLA, which clarified how to format references correctly. I also learned about the importance of maintaining academic integrity by properly attributing ideas to their original authors. The hands-on practice with database searches will enhance my ability to find credible sources more efficiently, which is really important for the research paper we are doing right now. Especially because the database we looked at was chemical, which would be really useful for the research paper. Overall, this workshop gave me essential tools to ensure my work is well-supported and ethically sound.
Workshop about pathway U :
The “PathwayU Assessment” Workshop was a really great experience that deepened my understanding of my interests and values, particularly in the domains of science and art. By guiding me to reflect on what I enjoy and how I define success, the workshop helped me identify career paths that align with my desire for independence, achievement, and excellence. The global visualization of my preferences highlighted the connection between my personal attributes and potential professional avenues, making the information feel relevant and actionable. This clarity not only enhances my academic choices, ensuring they align with my strengths, but also foster personal growth by encouraging me to pursue opportunities that reflect my open-minded personality and commitment to excellence. Overall, the workshop has brought motivation and keys to take meaningful steps toward my future.
Workshop about internship and study abroad :
I’m really happy about the workshop we had today because even if I can not participate in the study abroad programs, the internship parts are really interesting. For example, I’m already looking for an internship to do this summer, whether it’s in England or in the U.S, I really want to gain experience in my field, and I also want to do something of the time I have during the summer, to develop new skills, learn more about my intended major, and be able to contribute to diverse environmental missions.

So, it’s been almost a month since I’ve been here. Let’s be honest, I think the first week was the most challenging. I wouldn’t say that I was scared or homesick. But I was always overthinking about what people could think about me, what was going to happen the next day, and if I was going to stay alone. I arrived in a completely different environment with new people, a new language, and a completely different culture. Initially, I was lost. People were talking fast and sometimes I would just stop listening because my mind was going too fast.
But that was just the first few days. Three hours after being with the other international people, I was already feeling better and found new friends. I was feeling more comfortable quickly because as international people we can talk about our fears and the challenges we are encountering every day. Sometimes it’s not a big issue but just having people around you who understand what you are going through helps a lot. However, even if at the beginning I was a little bit lost, it has improved fast. After a week I was kind of used to the problems I had some time to understand and was focusing on understanding the context, or finally just asking people to say it otherwise, or just say it slower. By adapting to these small problems, I’ve never felt homesick. I see my friends here, sometimes feeling really homesick or just saying that they want to go home, and I can’t understand it. Maybe it’s because I was dreaming about it for so long that now I can’t see any bad points that would make me want to come home. However, I’m sure this time will come, probably when the hard exam will begin.
On the other hand, I was talking about how the internationals help me adapt to here, but the Americans help me as well. Interacting with American students has been eye-opening. Many of them work throughout the year to cover their tuition fees, which is a big contrast to the free education system in France. I’ve noticed that this financial responsibility seems to make students here more aware of the value of their education and more mature in handling real-life costs. Back home, many of my friends rely on their parents to cover expenses, which can lead to a more carefree attitude toward financial responsibilities.
Moreover, Every day, I engage in small talk with American students, asking questions like, “How’s your day going?” and trying to understand their casual expressions. For instance, Every evening I ask my roommate about the meaning of expressions I overheard but didn’t understand. Having people around who explain American nuances has been incredibly helpful.
That’s about the social part of my experience here, however, the academic one was pretty good as well.
Academically, I’m impressed with how professors teach here. Unlike in France, where each fact is often repeated to ensure understanding, professors here move quickly through the subjects. For example, in my biology class, the professor used practical examples and analogies to make complex concepts clearer. Initially, I found this fast-paced approach a bit disorienting, but I appreciate the depth and efficiency it brings.
By the way, at first, I was unsure about the value of the non-biology courses I’m taking. I questioned why I needed courses outside my major. However, I’ve grown to enjoy them. The public speaking course, for example, is helping me build confidence in presenting my ideas, which is essential for any career that I could choose. The critical thinking class is also proving beneficial, teaching me how to analyze and present my research more effectively. Despite the heavy workload, I’m managing to stay engaged in my studies and maintain a vibrant social life, which I find very fulfilling.
Therefore, these three weeks have been really enjoyable, I have proved to myself that I can go out of my comfort zone and follow my dreams. I am sure that it’s because it’s the beginning and that everything is new, but I hope I will continue to wake up happy and excited about the day coming.
Goals :
During this semester, I have some important goals that I really want to realize, to help me be better both in my field of study and in my studying method. I’ve always been really curious about the things around me, and studying at college allows me to dive deeper into these questions. However, even if I really like asking questions and studying, sometimes I might have a lack of organization and methods to work well.
First off, academically I have several goals. First, I want to keep my GPA above 3.5. I’ve always done well in highschool, and I want to maintain that level in college. I know that it’s going to be harder, but the resources available here are really helpful, and will help me maintain that goal. I plan to stay on top of my coursework, focused and engaged in class, and when it’s needed, I will make tutoring sessions and study groups to help me.
In particular, I’m eager to do great in my biology class. Even though it’s just an introductory class for now, I really enjoy it and I want to do well enough to take marine ecology next semester. I’ll make sure to read and connect the resources from the books and the lectures to solidify my understanding.
Another important goal is to improve my reading speed and concentration span. I often find myself re-reading pages because I lose focus, which slows me down. So I’ll try some techniques for better time management and practice reading strategies. It’s important to me, because besides the books that we have to read for class, I have several books that I would like to read to strengthen and broaden my understanding, especially in biology and chemistry. The sources from the library are really useful too, I used them a lot for my research and I’m willing to continue this way, to ensure my papers to have accurate and reliable information and data.
On the personal side, I’m working to enhance my writing and speaking skills. Since English is not my first language, I sometimes struggle with expressing myself clearly. I plan to join a writing workshop and work hard for the speech class. I’m also planning on asking help from the writing center if needed, to better use the resources that the school is offering.
Socially, I want to be more comfortable interacting with others. I want to join some campus clubs and get to know people better, which will help me feel more integrated and improve my communication skills.
I also want to dive into photography by taking pictures of sport events on campus. I’ve worked before with volleyball, so I’m excited to try photographing different sports and experimenting new styles. This will not only help me enhance my photography skills but also give me a creative outlet.
Looking ahead, I’m focused on my biology career. Particularly in conservation or laboratory work. To continue this way, I will look for possible internships during summer, or for the next few years, to develop and gain practical valuable experience and skills.
Indeed, these are my goals and the resources that I will use to make these goals a reality. Even if I don’t really like asking for help, I won’t hesitate to do so, because I really want to be the better version of myself here, and improve myself. Therefore, I will put all my efforts in following these goals and ways of improvement.
Key-Element of a Learner
If I were to choose an element to represent my philosophy of lifelong learning, it would be titanium. Known for its incredible strength, durability, and ability to withstand harsh environments, titanium mirrors the qualities I strive to embody as a learner: resilience, adaptability, and an enduring commitment to personal growth. Just as titanium can endure extreme conditions and still retain its integrity, I too aim to face the challenges of learning throughout my life with an unwavering spirit.
My upbringing aboard a sailing boat instilled in me an appreciation for exploration and constant movement. Life was a journey across seas, cultures, and perspectives. Each new port brought fresh challenges and opportunities for learning. In this dynamic environment, I learned to embrace change, seek out new experiences, and adapt quickly to unfamiliar situations—much like titanium’s ability to maintain strength and functionality in diverse conditions. Titanium’s resilience is a key characteristic that resonates with my own approach to learning. The material is known for its resistance to corrosion, making it a symbol of endurance. Similarly, I see learning as a lifelong process, one that requires persistence and the ability to bounce back from setbacks. I’ve experienced this firsthand through my journey in volleyball, where both victories and defeats became lessons in resilience. In the face of challenges, whether on the court or in other aspects of life, I’ve learned to rise again, stronger and more determined.
Moreover, titanium is highly adaptable. It is used in a variety of applications, from aerospace to medical implants, because of its versatility and ability to integrate into different fields. In much the same way, I believe that effective learning is not a one-size-fits-all process but something that must evolve with time. Just as titanium can be shaped into different forms without losing its essential properties, I strive to remain flexible in my learning journey, willing to adapt my methods and mindset depending on the circumstances and opportunities that arise. Whether it’s through sports, music, volunteering, or photography, I approach each new interest with the same eagerness to learn and grow.
The element of titanium also reflects my desire for lasting impact. Titanium is durable, and its impact is long-lasting—qualities that I hope to integrate into my approach to life. Like the metal, I want my contributions—whether it’s through the bonds I form with others, the memories I capture through my lens, or the lessons I impart as a mentor or friend—to be meaningful and enduring. I aspire to leave a positive imprint on the world, one that, like titanium, remains strong even in the face of time and change.In terms of my professional and personal growth, titanium represents the balance between strength and flexibility. As I continue to evolve as a learner, I understand the importance of remaining steadfast in my core values while remaining open to new ideas, challenges, and opportunities. My childhood experiences, from sailing across the Mediterranean to volunteering at a dog shelter, have reinforced the importance of learning from every corner of life. I believe that, like titanium, I must continuously test my limits, absorb diverse experiences, and refine my approach to learning so that I can thrive in any environment.
Ultimately, embodying the mindset of titanium will shape how I approach both challenges and successes in my future learning journey. Titanium’s adaptability and resilience are qualities I will carry with me throughout my life, ensuring that I am always prepared to learn, grow, and contribute to the world in meaningful ways. Whether I’m capturing the spirit of a moment through a photograph, embracing the strength of teamwork on the volleyball court, or pursuing a new passion, I know that, like titanium, I am capable of enduring, adapting, and flourishing.
