### Paper Towel Absorption Lab

To practice the skills used to design experiments

Purpose
• To see which brand is true to their claim
Problem
• Many brands of paper towels claim that they can pick up the most amount of liquid. How do we determine which towel does.
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.
• To design an experiment investigation (a fair test) to test the strength of three different brands of paper towels.
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
• 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.
