```					Science Third Grade

1) Build Background: Recess ball drop
2) Brainstorm what might make the ball bounce higher and more
times than other drops
3) Think Pair Share
4) Model ball drops at 25 cm and 30 cm
5) Ask the question, “Do you believe the height of when you drop
the ball effects the way a ball bounce?” Also the amount of
bounces?

Students will write a hypothesis for this experiment.
