Bubble Gum Lab Report
Backround
I know that everyone is using the same materials. We are all using Double Bubble and Wrigley’s Bubble
Gum. I have observed that based on the materials, we should get similar responses.
Hypothesis
My prediction is that even though we should be getting the same results, people might not chew the
gum long enough and the percent of sugar may be different for several people.
If some people chew the gum for less time, then their percent of sugar will be less.
Procedures
Procedure
1. Obtain a piece of wrapped bubble gum. Determine the mass of the gum (with the wrapper
on.)
2. Remove the wrapper and chew the bubble gum until all the sugar has been “swallowed”.
(about 3-4 minutes)
3. Find the mass of the wrapper while you are chewing, but don’t throw it away.
4. Return the chewed gum to the wrapper and find the mass. (gum absorbs a tiny amount of
water, so it is not necessary to dehydrate it or wait unit it dries).

Observations
Some people had lower sugar percentages since some people chewed the gum longer.
Analysis
My hypothesis was correct since I had said that some people would perform the experiment differently
than others and have completely different answers regarding the percent sugar in bubble
gum. However, I wonder how the experiment would have been different if people had been timed
while chewing the gum. And everyone chewed for exactly the same amount of time.
