Laura loved to chew gum- and she especially liked to blow bubbles. She wondered if the type of sweetener (real sugar or artificial sweetener) affected the size of the bubble. She assumed that they would be the same size. Laura got a pack of regular gum and a pack of sugar-free gum and chewed each. She blew the largest possible bubbles for each type of gum- then she measured the size of the bubbles to see if the sweetener type made a difference. What is the Independent Variable (IV)?

a)

The type of sweetener

b)

The size of the bubble

c)

The type of gum

d)

The number of bubbles
