Investigate the relationship between drop height and bounce height.
Step 1 - Using cardboard strips, students must construct their own 1m ruler or measure. (I bought a couple of sewing tape measures just in case)
Step 2 - Students prepare a data table like the following in 5cm intervals up to 100cm.
Drop Height | Bounce Height |
5cm | |
10cm | |
15cm | |
20cm | |
25cm | |
Step 3. Students work in groups of 3 - 4. One holds the ruler, one drops the tennis ball from the height, two watch the bounce height. Everyone records the data.
Step 4. Chart the data like below. (obviously results will vary)
Step 5. Discuss the formula
Drop Height = Bounce Height X ?
