No variable is tested.
When Jacob was cutting a bush, he found a caterpillar. He put the branch with the caterpillar in a cage. He will feed the caterpillar leaves from the plant. He hopes to watch it go through metamorphosis and change into a butterfly. Why is this NOT an experiment?

Multiple Choice
Renee rolls a steel ball down a ramp. She conducts multiple trials by releasing the ball from different heights on the ramp. For each trial, she measures and records the release height of the ball and the distance the ball travels away from the ramp before falling to the ground. The figure below shows the experiment.
In this experiment, which variable is the test variable (independent variable)
