Do you use sunscreen when you go to the beach or pool? If you use sunscreen do you know its SPF number? Do you know how long you can be in the sun without burning?

Many people enjoy going to the river in thesummer. Many sunbathers use sunscreen lotioins to protect themselves from the sun. The Sun Protection Factor (SPF) scale gives numbers that represent the length of time you can stay in the sun without burning if you have lotion on. Lets say you can stay in the sun with no sunscreen on for 10 minutes without burning. If you put on SPF 5 lotion, you can stay in the sun for 10 minutes X 5 or 50 minutes, or less than one hour.

For your assignment, you are to determine how long it takes you to get a sunburn in the sun. What might make getting a sunburn faster than normal? What can you do to perhaps be in the sun and not get a sunburn.
