In this Activity, students observe UV-sensitive beads that have been melted into flat disks, explore the temperature behavior of the disks, and then use the disks to investigate the effectiveness of different sunscreens. The Activity shows applications of chemistry in the real world. It could be used as an extension of a kinetics unit or to enhance a discussion of temperature-dependent reactions. The sunscreen testing can enhance consumer science topics similar to those found in the ChemCom curriculum.
