Independent &dependent variables

Ben makes five paper helicopters with different wing lengths. He drops them the same way from a height of two meters for five trials each. He records the amount of time it takes for each helicopter to fall to the ground.

What is the independent variable?

• Dropping the same way

• Wing Length

• Amount of time it takes the helicopter to hit the floor

• Dropping from the same height

The one factor that a scientist changes during an experiment.

• Controlled Variable

• Dependent Variable

• Independent Variable

The variable that is measured.

• Controlled Variable

• Dependent Variable

• Independent Variable

The factors that stay the same or are constant throughout the experiment.

• Controlled Variable

• Dependent Variable

• Independent Variable

In a controlled experiment, how many independent variables can be tested at a time?

• one

• none

• two or more

• how ever many makes sense.

Why is it important to have only one independent variable and to control the other variables when performing science experiments?

• So you can tell which factor is causing the change in the experiment.

• It does not matter, you can have as many independent variables as you want.
