Sunblock Experiment

How Does It Protect Us From the Sun?

Try this fun and easy experiment to learn how sunblock protects our skin.

Materials you will need:

  • Dark-colored construction paper
  • Sunblock with sun protection factor (SPF) of 30 or higher
  • A sunny day!

Do you get tired of slathering on sunblock all summer long? This quick experiment will show you why it’s important to protect your skin!

  1. Select a sheet of construction paper, and fold it in half.
  2. Squirt a blob of sunblock on one half of the paper. Have fun spreading it around and using your fingers to paint with the sunblock. Be sure you leave the other half of the paper clean.
  3. Head outside and find a sunny spot to leave your paper.
  4. After a few hours, observe the change. What happened to the side without sunscreen? How is the side covered in sunscreen different?
