KEEPING TRACK

1. STRIKE ONE! Pitch some balls. Keep a record of how fast you pitched each ball. Throw each ball three times. Find the average speed for each ball back at school.

2. Work with a partner. Use a yardstick. Hold your ball at 2 feet. Now bounce the ball on all the different surfaces. Record how high the ball bounced on each. Now hold the ball at 3 feet and repeat the test. Fill in the blanks after each. Did you get the same result?

	TWO FEET	THREE FEET

5. SURF'S UP! Do this with a friend. Have your friend count while you try to balance on the red feet. Then do it again on the blue feet. Count for your friend when he or she does the same. Record your results.
