The Quicker Picker-Upper

What brand of paper towel is the strongest and/or most absorbent?  My first and second grade tested four brands of paper towels for strength and absorbency this week.  They tested Viva, Bounty, Always Save, and Sparkle.  Which do you think is the strongest?  Which do you think is the most absorbent? We'll post our results next week.

Students first recorded the price of each paper towel roll.

Then, they used their senses to observe the paper towels.

Next, they measured them for strength using a spring scale.

They also tested them for absorbency. 

Students recorded their data in their scientific notebooks.
