__Problem:__ Do Different SPF's Make A Difference When Using Same Brand Sunblock? 

__Materials:__

 __Procedure:__
 * 1) four types of CVS brand sunblock, each one having different SPF's
 * 2) pack of developing paper
 * 3) masking tape
 * 4) file folder
 * 5) construction paper

 Determine your hypothesis. This is what you believe the results of the experiment will yield. Use a marker to draw a grid on a transparent sheet, leaving one space reserved for each brand of sunscreen and one for the control. If you are testing three brands of sunscreen, divide your grid into four equal sections. Do not apply sunscreen to the control section, which will display the effects of the sun with no ﻿﻿﻿protection﻿﻿﻿. <span style="background-color: #ffffff; color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 130%; overflow: hidden;">Label each grid section with a letter from the labels on the sunscreen. <span style="background-color: #ffffff; color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 130%; overflow: hidden;">Apply a thin layer of sunscreen to each section on the transparent sheet, making sure to to pair the correct sunscreen with its corresponding lettered section. Do not apply sunscreen to the control section. <span style="background-color: #ffffff; color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 130%; overflow: hidden;">Place the transparent sheet on top of a piece of construction paper and keep them in the sun for 45 minutes. <span style="background-color: #ffffff; color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 130%; overflow: hidden;">Bring both sheets back inside and allow them to sit for 10 minutes before determining the final results. Place the transparent sheet next to the construction paper as a reference point for which sunscreen was used in each section.
 * <span style="background-color: #ffffff; color: #000000; font-family: 'Times New Roman',Times,serif; font-size: 130%; overflow: hidden;">Label the different brands of sunscreen that you wish to test with letters, and place the labels on the bottles. If you are testing 3 brands, for example, the brands will be represented by letters A, B and C.

Compare the results of your experiment with your original hypothesis. Use this information to answer the following questions: Was your hypothesis correct, and why or why not? Why is it important to wear sunscreen? What effect, if any, did a lack of sunscreen in the control grid yield?
