Find out with this experiment about the sun and potentially harmful ultraviolet (UV) rays.
Use UV-sensitive beads that change color when exposed to sunlight to understand how the Sun produces different wavelengths of light and what materials can protect us from those potentially harmful rays. You can also use black light as a source of UV light.
Project Extension: you can use different SPF sunscreens to cover the beads and see if that helps protect them from the harmful UV rays. You can really tell why your parents say it is important to put on sunscreen when you go outside on a sunny day or at the beach!
