Bubble Gum Experiment
The purpose of this experiment is to use the Scientific Method to solve a
problem.
Materials:
2 small pieces of wax paper
String
1 meter stick
3 different brands of bubble gum
1 plate
Observations:
Bubble Yum____________________________________
Bubblicious_____________________________________
Hubba Bubba____________________________________
Problem: Which brand of bubble gum blows the biggest bubble?
Hypothesis:
If _________________________________________ then ______________________________
______________________________.
Procedure to find the average bubble size for each brand of bubble gum.
1. Chew Bubble Yum for 3 minutes then blow a bubble.
2. Using a string, you will measure the diameter of the bubble. Put the string on the meter
stick to measure the distance in centimeters.
3. Repeat this once and add the data to trial 2.
4. After the second bubble is measured, place the chewing gum on the wrapper on top of
your plate.
5. Repeat steps 1-4 with each brand of bubble gum.

Which brand of gum is best at blowing bubbles and why?
___________________________________________________________________________
Problem: How does stretchability relate to bubble size.
Hypothesis:
If _________________________________________ then ______________________________
______________________________.
Procedure to find the stretchability for each brand of gum.
1. Roll Bubble Yum into a ball.
2. Hold the gum by using wax paper. Your partner will hold the same piece of gum with
another piece of wax paper. Hold the gum near your chest, begin to walk slowly
backwards.
3. Have a third person hold a meter stick to measure the distance in centimeters the gum
stretched before breaking.
4. Record the data below.
5. Repeat step 1-4 for each brand of bubble gum.
Bubble Yum ________________ cm
Bubblicious _________________ cm
Hubba Bubba________________ cm
Is there a relationship between bubble size and stretchability? If so, what is the relationship?
