This document summarizes a student's science experiment testing the absorbency of different paper towels. The student hypothesized that Bounty paper towels would be strongest based on their design. The experiment involved placing drops of water in the center of Bounty, Brawny, and Sparkle paper towels and measuring how many glue sticks each could hold without tearing. Test results showed Brawny was able to hold the most glue sticks on average, not Bounty as hypothesized. The student concluded their hypothesis was incorrect and that Brawny performed best in absorbing water and supporting weight.

QUESTION:
WHICH PAPER TOWEL IS THE
STRONGEST
HYPOTHESIS:
(If we put drops of water in the middle of
each paper towel (Bounty, Brawny, and
Sparkle) and see which one can handle the
most glue sticks on it then we think
bounty will be stronger.

10.Try each paper towel three

13. Graph Data on paper
CONCLUSION:
(If we put drops of water in the middle of
each paper towel (Bounty, Brawny, and
Sparkle) and see which one can handle the
most glue sticks on it then we think
bounty will be stronger.
We first filled the pipets with water then we put water
in the middle of the paper towel then we put the glue
sticks on the each paper towel and then we saw which
paper towel held the most glue sticks and we did that
three times each to every paper towel.
Our data may be off because on some tests because
we might of used to much water on some test. Another
reason our data might be off is we might have lost track
of how much glue sticks we put on the paper towels.
No our test did not prove our hypothesis that Bounty
is the strongest our test proved that Brawny was the
strongest. We thought Bounty was going to be strongest
because of the design of the paper towel but after all
Brawny was the strongest.
