"1.In this experiment I am going to test the efficacy of sunscreen spray and lotion ranging from SPF 15 to SPF 100. 2. I am trying to find the answer to this question because everyday people suffer from skin diseases and skin cancer especially. My family has a history of skin cancer like my dad who is trying to get rid of skin cancer on the side of his face. 3. The experiment produced results. They are as follows. The UV Detector indicated that the UV index of that time was 5.5. The results displayed that the SPF 100 lotion was the best and the SPF 15 spray was the worst. The lotion 100 was first, lotion 50 was second, lotion 30 was third, the spray 100, spray 50, and lotion 15 tied for 4th, the spray 30 was fifth, and the spray 15 was sixth and the worst. 4. I think that the results of this experiment can show what the best option to protect your skin is. "
