Series1

Ms. March heard that a new toothpaste makes your teeth whiter. She wants to know if that is true, so she buys the new toothpaste to try it. Help Ms. March design an

experiment to find out if the toothpaste is as amazing as the television commercial suggests.

Ms. March’s question: What is the affect of the new toothpaste on the color of teeth?

Ms. March’s hypothesis: I think that the new toothpaste will make teeth whiter than the old toothpaste does.

Design a procedure that Ms. March can follow to test the toothpaste.
