Nature of Science

Scientists have MANY trials so their results are 

• countable
• graphable
• reliable
• hard to understand

The one factor that a scientist changes during an experiment. (It affects the results of the experiment).

• Controlled Variable

• Dependent Variable

• Independent Variable

The variable that is measured. It is the result of the experiment.

• Controlled Variable

• Dependent Variable

• Independent Variable

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
