Aim: To record the relationship between the height where the ball is dropped from, and the ball's first bounce
Equipment: Metre ruler, tennis ball
Hypothesis: I think the ball will not bounce that high, because we are about to use a tennis ball which is not good enough to use
Method: ( My own opinion )
1. Get a partner and make her or him hold the metre ruler
2. Then drop the ball and make your partner record it.
3. Keep repeating it.

Discussion: We talked about why did the ping pong ball bounces high. It is because it's a plastic.
Results: My hypothesis is wrong. It is because we didn't use a tennis ball, we used a ping pong ball. I think my teacher mean ping pong ball but I'm thinking about a tennis ball.
