Medium
Swimsuit Fabric and Water Drag
9. Swimsuit Fabric and Water Drag
Wrap a weighted container in three different swimsuit fabrics and race them to the bottom of a pool to see which creates the least drag.
Hard
Octyl Salicylate Concentration and UV Blocking
10. Octyl Salicylate Concentration and UV Blocking
Coat glass with rising amounts of a sunscreen ingredient and watch the UV meter drop as concentration climbs.
Medium
Measuring Sunscreen UV Absorption
11. Measuring Sunscreen UV Absorption
Dissolve sunscreen in ethanol and measure its UV absorbance at different concentrations to calculate how effectively it blocks ultraviolet light.
Hard
Sunscreen SPF and UV Protection
12. Sunscreen SPF and UV Protection
Coat glass sheets with different sunscreens and use a UV meter to find out whether doubling the SPF actually doubles the protection.
Hard
Sunscreen, UV Light, and Bacteria Survival
