Science Fair Project Template Each of the following slides are designed to present a step in your science investigation using the Scientific Method. Write all your project information in the corresponding slides. Slide 9 between Data and Results contains an Excel connection to create a bar graph. You can use all, some, or replace the clip art.

Problem Statement Which brand of paper towel is the most absorbent? (Title: Paper Towels to the Rescue!)

3
Variables Constant Variables: Tray Graduated cylinder 5ml of water at a time Funnel Deli container Manipulated Variable: Brands of paper towels Responding Variable: The paper towel that is the most absorbent.

4
Hypothesis: If we test Bounty, Sparkle, Family Values, Clear Value, and the school’s paper towel, then Sparkle will be the most absorbent.

5
Materials Bounty paper towel Sparkle paper towel Family Values paper towel School’s paper towel Clear Value paper towel Water Graduated cylinder Tray Funnel Deli container

6
Procedures 1. Pour 50ml of water in the graduated cylinder. 2. Pour the water in the cup. 3. Submerge a sheet of paper towel into the water. 4. Lift the paper towel out of the water and once it starts dripping slowly place it in the deli container. 5. Pour the water that is left in the cup into the graduated cylinder. 6. Measure the water. 7. Subtract the amount of water that is left from 50ml. 8. Record that number on your data table. 9. Repeat steps 1-8 using the SAME brand of paper towel. 10. Repeat steps 1-9 with the other brands of paper towel.

Results Bounty absorbed 25ml of water. Clear Value absorbed 26ml of water. Family Values absorbed 15ml of water. Sparkle absorbed 22ml of water. The school’s paper towel absorbed 17ml of water. Finally, Kirkland absorbed 46ml of water.

11
Conclusion Our hypothesis was not supported by our experiment. We thought Sparkle would have been the most absorbent, but Kirkland was the most absorbent. We realized that Kirkland was way bigger than all the other paper towels. It’s not fair. Next time we will cut them so that they are equal sizes.

12
Application This experiment can help me in life because I know which paper towel to get. We can show our parents the data from our experiment to prove that Kirkland is the most absorbent paper towel.

Abstract We wanted to find out which brand of paper towel is the most absorbent. We hypothesized that Sparkle would be the most absorbent. After we tested 6 different brands of paper towels, Kirkland was the most absorbent.
