Hypothesis
My hypothesis is that the marble will roll further because it has more weight, its small and is mostly used for races.
Steps
We are going to use this metre stick for are ramp.
The we are going to get a marble and a ping pong ball then roll it down the ramp one at a time ( 3 x each )
Results
| Roll | Marble | Ping pong ball |
| 1 | 15 | 21 |
| 2 | 17 | 19.3 |
| 3 | 13 | 20.1 |
| Average | 15 | 20.1 |
Conclusion
The hypothesis was incorrect I thought the marble would go faster because of its weight, but i found out that the ping pong ball when faster when it hit the ground ( because its light I think) .
