This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays. Learners will hang apple rings in the Sun and monitor changes in the apple composition as it suns. How does the apple in the Sun differ from an apple kept inside away from the window? Included are suggestions for taking the activity further, including ideas for creating a more experimental investigation and positing a hypothesis.
