Final Jeopardy!
Scientific Investigation
Make your bid!!
Amanda does an experiment to determine
which brand of paper towels absorbs the most
water. She buys three different brands of paper
towels. She spills ½ cup of water on the table
and absorbs it with a paper towel, recording
how much water is left on the table. She
repeats this with each paper towel.
This is the responding variable.
How much water the paper towel
absorbs.
