Science Wow Week - Bouncing Balls

The Puriri Wha classes finished off our Science Focus for this term  with a rotation. Here are a couple of videos of the experiment the children did with me.
They were asked to observe and think about what happens when they:
1. drop a basketball and a tennis ball on the ground from the same height.
2. place the tennis ball on top of the basketball and drop them
3. place a ping pong ball on top of the tennis ball which is on top of the basketball.

Unfortunately I couldn't video a successful bounce but there was lots of excitement and laughter when groups worked out how to get the balls bouncing.

Try this experiment at home, making sure you are doing it away from windows and gutters, and write a comment below about what you observed.

Note: the countdown is necessary 😁
