On Tuesday morning Jim came to our classroom to show us how to do science fair experiments.
We had to find out:
Will a marble roll further down a carpeted ramp or a smooth ramp?
Our class found out that a marble would go further with a smooth ramp and not with a carpeted ramp. We had these stickers to measure how far it would go. Jim told us what to do first. Then after that we changed either the weight or the size of the marble. The smallest weight one went the most far away and beat the bigger size. Afterwards we peeled the stickers off.
