1 Copy the chart on the next page into your science journal so you can record your experiment results.

2 Stand on the bathroom scale. Write down the number. This is your weight and a measure of how much gravity is pulling you down.

3 Watch the dial as you bend your knees, stand on tiptoes, and then jump. Did you notice the number change? Did the number go up or down?
