  1. Paper Towel Absorption Lab To practice the skills used to design experiments

  2. Purpose • To see which brand is true to their claim

  3. Problem • Many brands of paper towels claim that they can pick up the most amount of liquid. How do we determine which towel does.

  4. Background Information: • Since paper towels are used to pick up liquids, the volume of liquid it can hold is important. The amount of liquid a towel can absorb can be measured by the volume of liquid it picks up.

  5. The Task: • To design an experiment investigation (a fair test) to test the strength of three different brands of paper towels.

  6. The Best Paper Towel Lab • Step1- Identify Variable Independent Variables (what you will change, or the difference between the groups) Dependent Variable (what you will observe and measure, the data that you will collect). • Step2- Write a Hypothesis Write a HYPOTHESIS that shows the expected relationship between the variables. Use the IF, THEN statement. • Step3- Procedure • Step4- Record your data • Step5- Graph your data • Step6- Analyze your data: What story does the graph tell? What do you know about the effect of the independent variable on the dependent variable? Do you see a relationship? • Step 7- Write a CONCLUSION. Answer your original question. (Which paper towel absorbed the most liquid?) Accept or reject your hypothesis. Use actual data (real numbers) to provide evidence fro what you say.
