Tyrone and Valerie wanted to determine what feature of a paper airplane would cause it to fly the farthest. Tyrone made his airplane with wider wings than Valerie’s airplane. Valerie’s airplane had shorter wings, and the plane was also narrower and longer than Tyrone’s. After testing the two airplanes several times, the evidence shows that Tyrone’s airplane flew farther through the air than Valerie’s airplane.

Describe why the investigation above is not adequate to explain which airplane feature caused Tyrone’s airplane to fly farther than Valerie’s.

Using what Tyrone and Valerie have already observed, suggest a possible hypothesis regarding one feature of a paper airplane.

Identify the independent and dependent variables. Describe, in detail, a procedure to test your hypothesis. Identify the controlled variables.
