What is UV Ray Blocking Effectiveness Lab about?

The lab activity focuses on testing various items for their effectiveness in blocking UV rays, with a data table recording the time taken for UV beads to change color. Sunscreen was determined to be the most effective item, as it contains both organic and inorganic compounds that either absorb or reflect UV rays. The higher the SPF, the more protective the sunscreen formulation is against harmful UV radiation.
