Overview:

This science experiment is designed to demonstrate how sunscreen counteracts, or blocks, the effects of the sun’s ultraviolet (UV) rays.

How does sunscreen work? Does using sunscreen really make a big difference to our skin? Do we really need to use it? You tell us at the end this experiment
Materials Needed:
Construction paper (Darker is better)

Did you know, you can harness the sun’s renewable energy to purify contaminated water? With the sun’s heat and the help of the water cycle, we can take dirt...
