Tips for a good presentation slides 1.Font size should be no less than size 20. (this is Arial size 32) 2.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. 3.Choose colors that contrast very well (background and text) 4.Exclude distracting animations or slide transitions.

The Effect of Air Pressure on Bounce Height Albert Einstein and Charles Darwin

Purpose The purpose of this study is to identify the effect of air pressure on the bounce height of regulation sized basketballs.

Experimental Set-up

Table 1. Bounce height of three basketballs inflated at different pressures Trial #Low pressure ball bounce height (cm) Medium pressure ball bounce height (cm) High pressure ball bounce height (cm) Average

Discussion- Explanation of Results 1.Pressure does effect bounce height 2.Elasticity of stretch rubber increases as the pressure increases. 3.Low pressure ball had insufficient elasticity 4.Elasticity reached a maximum in the medium ball.

Discussion- Implications 1.Basketballs need to bounce well for dribbling 2.Sufficient pressure is important for a good bounce 3.Over-inflating balls does not have a benefit
