  1. 1) In the helicopter experiment, what was the independent variable • The independent variable was the folding of the blades in different directions. • Remember the independent variable is the variable that the experimenter changes, usually followed by the “if” statement, and usually found on the “x” axis. M I X • Also known as the “cause”

  2. What is the problem in Bonita’s experiment? • Will adding paper clips for mass stabilize the helicopter and make it stay in the air longer?

  3. What is Bonita’s hypothesis? • If additional paperclips are added to the helicopter, then the helicopter will be stabilized resulting in a longer flight time.

  4. What is her independent variable? • Bonita’s independent variable is the addition of paper clips ( weight ) to the helicopter.

  5. What is her dependent variable? • Bonita’s dependent variable is the amount of time the helicopter stays in the air.

  6. What was the dependent variable? • The dependent variable is the direction of spin, clockwise or counterclockwise. • Remember the dependent variable is the variable that changes because of the independent variable, usually followed by the “then” statement, and usually found on the “Y” axis. D R Y • Also known as the “effect”

  7. List three things you should try to keep constant each time you try this experiment. • Hold the helicopter in the same place • Holding it at the same height • Make sure there is no cross breeze • Usinging the same helicopter • Adding no extra force when letting it go
