The summary at the end of an experiment that explains the results is... 

• conclusion
• procedures

• responding variable

The information you collect while doing your experiment is called

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 dependent variable?

• Dropping the same way

• Wing Length

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

• Dropping from the same height

What is a control?

• What a scientist changes in an experiment to test their hypothesis

• What scientist measure to see if it responded to a change

• What happens when you do an experiment

• What you keep the same throughout all experimental groups

A student wants to test the type of exercise that affects heart rate.

She walks, skips and runs.

The dependent variable is

• Heart rate

• Type of exercise

• Testing the exercises on the same student.

• Testing the exercise on different students
