Will their results

• We get all the types of gums and Reichel chews each
kind and blows a bubble. We will measure the size of
each type of bubble gum. To get the right amount of
each type of bubble gum, we will weigh it before we
chew it because it has to be the same size and weight.
Reichel will chew each bubble gum for ten minutes.
Reichel will blow each bubble gum ten times.
• We are going to measure each bubble by using a ruler.
The ruler will have two unbent paper clips so it will be
easy to measure each bubble. One is on the end of
one side of the ruler, and the other paper clip will be
used to move through the ruler.
• Jennifer will record each size of the first ten
bubbles blown. We will add up the ten sizes, then
divide that number with 10 to see what the average
size of each type of bubble gum.
