7th
Week of 8/19-23:
Homework due Friday, 8/23: I will explain the homework on Tuesday…Write a step-by-step procedure (minimum five
detailed steps) for testing the absorption of 3 brands of paper towels. You are given the problem and the
independent/dependent variables. Taking these into account, design a controlled experiment to help you determine which
paper towel absorbs the most water. Think of ALL the things you need to control to make sure they don't get in the way,
and how you are going to MEASURE how much each towel can absorb. This will take a lot of thought and planning. MUST
BE TYPED with proper paper heading. PLEASE print your procedure and turn in to the basket.
