1. Ball and ramp controlled study

2. Problem
How does the release distance affect the bounce distance of a golf ball from bounce 1 to bounce 2?

3. Hypothesis
I predict the larger release distance of the golf ball will make the ball bounce further from bounce 1 to bounce 2.

4. variables
The controlled variables are the ball , angle of the ramp , and the floor surface.
The manipulated variables are the release point and the distance.
The dependent variables is the distance from bounce 1 to bounce 2.

5. Materials Carbon, paper , googles, golf ball, graph paper, lab report,
masking tape,
meter tape,
Scott towels,
16 D nails,
2 PVC piping.

6. procedures
1draw plan/sketch 2 get materials 3put on googles 4construct ramp 5 put nail in 10cm mark 6put down paper towel 7place carbon paper on top of paper towel 8 drop ball

7. Possible explanations
The greater release distance the greater the distance from bounce 1 to bounce 2 because the ball picks up speed and force the greater the release

8. additional questions #1
What happens to the bounce distance as the release distance increases?
The bounce distance increases when the release distance increases.

9. Additional questions #2
What is another variable that you would like to manipulate? Write down a problem statement for this new experiment to possibly investigate ?
How far would a bouncy ball travel from bounce 1 to bounce 2

10. observations
There is a 43 cm distance between bounce 1 and bounce 2 for the 10 cm release.
There is a 51 cm distance between bounce 1 and bounce 2 for the 20 cm release.
There is a 78 cm distance between bounce 1 and bounce 2 for the 40 cm release.
There is a 99 cm distance from bounce 1 to bounce 2 for the 60 cm release
There is a 114 cm distance from bounce 1 to bounce 2 for the 80 cm release
There is a 112 cm distance from bounce 1 to bounce 2 for the 85 cm release

11. conclusion
In conclusion the greater the distance, the greater the distance from bounce 1 to bounce 2. This is because the golf ball picks up speed and force the higher the release. Although for the 85 cm release the distance between bounce 1 to bounce 2 decreased . This may have been because of a variable we were not aware of.
