Forces and Motion: Marble run

On Tuesday, September the 15th, we made marble runs and we finished them off this morning. The goal was to make the marble last 20 seconds long on the marble run that we made. Me and my friends made a marble run and ours went for 3.58 seconds. That may not seem very long but we bet three groups.

We were doing the marble to finish off our topic, forces and motion. We were learning mainly about gravity and friction.

I enjoyed making the marble run because it was a lot of fun and it was very interesting.

I found it challenging because we had to keep improving it and fixing up our mistakes but other than that, it was really fun.

Next time I would try to make it last longer and try to slow the marble down.
