In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
