Sunscreen Experiment

Heres what you need:
-Sunscreen (lotion not spray)
-Black Construction Paper
-White Crayon

Procedure:
1. Fold the piece of black construction paper in half.
2. Put a VERY SMALL dab of sunscreen on one side of the paper.
3. Let your child smear the sunscreen on the half of the paper it is on.
4. With your white crayon label each side sunscreen and no sunscreen
5. Put the piece of construction paper in the sunlight for most of the day
6. After 5 hours check the piece of paper. You should be able to see that the side that has sunscreen stayed dark and kept it's color vs the side without the sunscreen. The side that did not apply sunscreen will be faded and spotted.

We did this experiment in class and after  just an hour there was many white spots where the paper had faded on the side without sunscreen. The side with sunscreen kept it's color intact!

Our class discussed how sunscreen protects our skin just like it protected the paper. We also discussed how some sunlight is good for our bodies, but too much is harmful. Without sunscreen, the sun would hurt our skin. We also talked about other ways to protect our skin from the sun such as hats, clothing, shade, etc.
