My project is about sunscreen testing with mineral, chemical, and homemade sunscreen. I chose this project because it seemed fun and usefull. My results were that the mineral sunscreen worked the best, and the homemade didn't work. My project is important because you don't want to get sun damage.
This is a very relevant and well-designed experiment about sun safety! I really liked how you compared chemical, mineral, and homemade sunscreen using cyanotype sun paper (pages 5-6). Your procedure was clearly explained, and I appreciate that you repeated the experiment after identifying an issue in the first round (page 11). That shows strong scientific problem-solving. Your background research on UVA, UVB, and UVC rays (page 7) and SPF differences (page 8) demonstrates a good understanding of how sunscreen works. The results photos (page 9) clearly show that mineral sunscreen provided the most protection, and your conclusion (page 10) logically matches your findings. I also appreciate that you acknowledged limitations, such as only using one brand and not testing on real skin (page 11). That shows scientific maturity.
This project addresses an important health topic and communicates clear recommendations. Keep exploring real world science questions you are developing strong experimental and analytical skills!
Well done! Sun protection is so important in Arizona, and you did a good job researching why. Thank you for sharing your project!
