1. QUICK GET ME A PAPER TOWEL, I NEED TO CLEAN THIS UP
NAME: Douglas Chester DATE: September 10, 2009 PERIOD: 4 TEACHER: Mrs. Dorsey / Mr Hanson
QUESTION:
Which paper towel will absorb the most?
HYPOTHESIS:
If we take Bounty, Brawny, and sparkle and dip them in a
55 milliliter cup of water then Bounty will absorb the
most because it is a good picker upper. Mr. Hansen the videos didn’t save.
MATERIALS/APPARATUS:
1. Measuring cup
2. Brawny paper towels
3. Bounty paper towels
4. Sparkle paper towels
5. paper
6. water
7. pencil
8. computer

2. Get the bounty paper towel. BRAWNY 22.5 24.5 31.5

6. Then write down what we measured on a graph. 30.0 31.5

8. Repeat 1-6 with Brawny and Sparkle. 24.5

9. Draw our conclusion.
CONCLUSION: 20.0
Our hypothesis was that if we take Bounty,
Brawny, and Sparkle and dip them in a 55 milliliter cup 10.0
of water, then Bounty will absorb the most because it is
a good picker upper.
At first, we took a 55 milliliter measuring cup 0
Test 1 Test 2 Test 3
and filled it with water. Then we took the Bounty paper
towel and dipped it in the water for 30 seconds and
then we let it drip until it stopped. Then we measured Bounty Brawny Sparkle
how much was left in the cup and subtracted to see
how much it absorbed. Then we made a graph on the
computer, and recorded our data. Afterwards we
measured Bounty 2 more times. Eventually we Mr. Hansen the videos didn’t save.
experimented with Brawny and Sparkle(3 times). Now
we are drawing our conclusion.
Our data is off because different people did the
experiment. Some of them might have accidentally
squeezed it more the others. But our data was still
pretty close to the same each time.
Our experiment proved that our hypothesis
was true because we had predicted that Bounty would
be the most absorbent because it is a good picker-
upper and it costs the most.
