The purpose of this study was to determine when sunscreen needs to be put on and when sunscreen does not need to be put on the human skin. Sunscreen works like little mirrors, reflecting some of the sun’s ultraviolet radiation off of the skin. UV beads with sunscreen on them were put in water and other places for different amounts of time and then put on an ultraviolet scale to see how much ultraviolet light was on the beads. It was determined that sunscreen does protect the skin from ultraviolet radiation, however, not completely. When soaked in water, some of the sunscreen comes off of the beads, which leads to a smaller amount of protection on the human skin. =====

In the future, it would be interesting to test more brands of sunscreen so the ingredients in sunscreen that work the best can be more clearly seen. A follow-up on the ice cubes and sunscreen experiment would also be very interesting to find out if sunscreen reflects not only rays but also heat. =====
