The Effect of Different Brands, SPFs, Types of Sunscreens, and the Amount of Sunscreen on how well They Protect Against UV Light
Additional Project Information
Questions and Answers
1. What was the major objective of your project and what was your plan to achieve it? The major objective is to find out the effectiveness of different kinds of sunscreens. Therefore, it can provide a guide for buying different sunscreens. The plan to achieve it is to design experiments to find out.
a. Was that goal the result of any specific situation, experience, or problem you encountered? Yes. Because there are so many choices of sunscreens on the market and their prices are very different. It is very hard to make the right choice.
b. Were you trying to solve a problem, answer a question, or test a hypothesis? I was trying to solve a problem and also test my hypothesis.
2. What were the major tasks you had to perform in order to complete your project? The major task is to design the experiments to test out my hypothesis.
a. For teams, describe what each member worked on.
3. What is new or novel about your project? The novelty of my project is to use UV light card to mimic the human skin and visualize the UV effect on human skin.
a. Is there some aspect of your project's objective, or how you achieved it that you haven't done before? I am not sure how well it will work to use the artificial UV cards to mimic human skin.
b. Is your project's objective, or the way you implemented it, different from anything you have seen? The experimental results were more complicated than I initially expected.
c. If you believe your work to be unique in some way, what research have you done to confirm that it is? The UV cards I got were used to test the strength of UV rays in the sun light to provide a guidance for choosing sunscreens. They were not designed to study the effectiveness of sunscreens. Therefore, my experiments were unique.
4. What was the most challenging part of completing your project? The color changed happened very fast and the color changed were not easy to see from naked eyes.
a. What problems did you encounter, and how did you overcome them? The color change speed was very fast for each card. To solve this problem, I had to shorten the exposure time. In addition, the color change was not easy to see from naked eye. To solve the problem, I had found an app tool that can measure the color scientifically. The color was characterized by color coordinates, which can precisely define the color.
b. What did you learn from overcoming these problems? What I learned is that to think creatively and do more research.
5. If you were going to do this project again, are there any things you would you do differently the next time? It is difficult to determine whether SPF truly matters in an experiment like this, however there are many sources with real, practical scenarios that prove the importance of SPF. There is no distinct difference between how well chemical and mineral sunscreens perform, however mineral sunscreens must be applied more thickly. Some things I would do to improve the experiment would first be to minimize the area for human error and outside factors. The cards I had used are reusable, and revert back to white after it is brought back to an environment without exposure to UV light. If I were to try this experiment again, I would also see how long each sunscreen would take to revert back to normal, or find a way to see how water resistant each sunscreen was. I would also search for a more efficient and accurate way to represent how it would work on actual skin.
6. Did working on this project give you any ideas for other projects? Yes. I have learned a lot of lessons from this project. The experiments may not clearly give the results you expect. It is important to design the experiments well and do thorough preparation before doing experiments.
7. How did COVID-19 affect the completion of your project? No effect.
