1. The effect of air pressure on bounce height.
Albert Einstein and Charles Darwin
Presenter’s Role
- Read slide

2. Purpose
The purpose of this study is to identify the effect of air pressure on the bounce height of regulation sized basketballs.
Presenter’s Role
- Read slide

3. Experimental Set-up Presenter’s Role
- Describe pictures and experimental set-up

Presenter’s Role
- Discuss observations and result trends

5. Discussion- Explanation of Results
Pressure does effect bounce height
Elasticity of stretch rubber increases as the pressure increases.
Low pressure ball had insufficient elasticity
Elasticity reached a maximum in the medium ball.
Presenter’s Role
- Elaborate on points from slide

6. Discussion- Implications
Basketballs need to bounce well for dribbling
Sufficient pressure is important for a good bounce
Over-inflating balls does not have a benefit
Presenter’s Role
- Elaborate on points from slide

7. Tips for a good presentation slides
Font size should be no less than size 20. (this is Arial size 32)
Do not write too much text on the slides, most lines will be point form, no more than 3 to 4 points (bullets) per slide.
Choose colors that contrast very well (background and text)
Exclude distracting animations or slide transitions.
