Bubble Gum Physics
Obtain a piece of bubble gum from your teacher and start chewing to get ready for the experiments with your
table mate!
1. For this experiment, you will conduct three trials (two times each) to determine the number of chomps you can
do in 60 seconds by following the condition that stated on the table below. A chomp is defined as a “big chew”,
or the kind that usually causes you to get caught with gum!
2. Use a timer to determine the number of chomps you can do in 0, 15, 30, 45 and 60 seconds. Record your data
in the table below. Repeat the process for the other trials.
Time (s)
Trial 1: constant chewing
Average number of
chomps
Trial 2: slow to fast
Average number of
chomps
Trial 3: fast to slow
Average number of
chomps
0
15
30
45
60
3. Construct a distance-time graph to show your results by plotting the average number of chomps as the
distance (meter) against time (seconds). Be sure to label each graph! (y-axis is the distance, x-axis is the time)
4. Calculate your chomping speed at each point (0, 15, 30, 45 and 60 seconds) using the data from your
experiment. Assume that the average number of chomps of each trial is the distance travel (m).
Speed = Distance (number of chomps) ÷ Time

5. Construct a speed-time graph to show your results by plotting the speed (m/s) against time (s). Be sure to
label each graph! (y-axis is the speed, x-axis is the time)
