Ask students what they do to prevent sunburn. Avoid prolonged sun exposure. Avoid sun exposure when the rays are the strongest. Cover exposed parts of the body. The best way to protect against damage is to wear sunglasses that screen the UV rays.
Hats can also protect the eyes and face from damage.
Initiate a discussion of sunscreen basics. Have students examine a bottle of sunscreen. Ask students what sunscreen is. Sunscreen is a mixture of chemicals that block ultraviolet light. SPF is how much longer you can stay in the sun without burning if you apply sunscreen compared to being exposed without the sunscreen.
