Introduction

Find a partner to do this activity with. Chew your piece of bubble gum for a minute

or two until it is soft enough to begin blowing bubbles. Blow a bubble and hold it,

allowing your partner to measure its diameter in centimeters as carefully as possible.

Turn to your partner and do the same with his/her bubbles. You will have 20 bubble

measurements total. Share your bubble measurements with the class so that you

have class data to answer the following questions.
