Science Experiment Basics
The investigation
Jarrah wants to find out whether a steeper ramp makes a toy car travel farther. She raises one end of the same ramp using different numbers of blocks. For each height, she releases the same car from the same starting line without pushing it. She measures how far the car rolls along the floor. She repeats each test three times and calculates the average distance.
