Chemistry Unit Study Game 1

Mr. Lee was staring at the gum selection at the store the other night and he was wondering, which brand of gum actually produced the biggest bubbles? So, he asked his 11th grade Chemistry students for some help. He had two student volunteers who would be the “testers” of the gum. He selected BubbleYum and Double Bubble as the brands to test. They discovered that BubbleYum created the largest bubbles!

What is the independent variable in this experiment?

• The student that chewed the gum.

• The brand of gum.

• The size of the bubble

• How many pieces of gum they chew.
