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

• Construction paper (Darker is better)
• Sunscreen (SPF 30+)
• Leaves and flowers (or any other item to "print")
• Hands are popular!
• A Sunny afternoon

Instructions:

1. Layout your construction paper (preferably inside, then taking it outside after 15mins)
2. Generously apply your item of choice with sunscreen (leaf, flower or hands) and make your print! If you use an item instead of your hand, make sure to put a rock/stone to hold it down properly.
3. Once the construction paper is printed with sunscreen, place the paper in the direct sunlight (Preferably outside)
4. Leave your experiment in the sun for at least 3 hours for best results.

Outcome:

When sunscreen is applied to the paper, the chemicals in the sunscreen should absorb the UV radiation and prevented them from bleaching the paper.
