Sunscreen Experiment

Scripture: Joshua 10-11, 18

Learning Objectives:

  • Students will learn God keeps His promises.
  • Students will learn partial obedience to God is not obedience and can bring consequences.
  • Students will learn the choices people make can affect future generations.
  • Students will learn how to test sunscreens using a UV monitor.

Guiding Question: Why does God perform miracles?

Materials: construction paper, various sunscreens, sunny spot

Procedure: Review the story of Joshua and the day the sun stood still with students. Talk about the miracle involved. Explain that God uses miracles to remind people He is God and can control anything – including the sun. Remind students to trust that God can perform miracles in any situation that seems impossible if it is in His will.

Introduce the activity. Tell students they are going to compare different sunscreens to see which one is most effective. Draw enough squares on the construction paper for each sunscreen you want to compare. Put the same amount of each sunscreen on the paper – one sunscreen per square. Place the paper in a sunny spot. Bring it inside in 2 hours and observe. Whichever sunscreen you can still see the most is the most effective.

Additional Questions: What is the difference between spray and lotion sunscreen?

Supplemental Activity: Have students repeat the experiment, this time comparing the difference between spray and lotion sunscreen.
