Marbles in Motion
By Hanna Rhoads (partner: Alex Watts)
Materials
●partner
● assorted marbles and balls
● straws
●cafeteria trays
●note book
●pencil/pen
●tape measure (cm)
Observations
The bigger the ball the more likely it is to fall off the track. The smaller the ball the more likely it will stay on the track. The more mass the more likely the ball will not go to the end of the tape. The less mass the more likely the ball will go to the end of the tape. The more dense the ball the less likely it is to make it to the end of the tape and the less dense the more likely it will make it to the end of the tape.
Results

Conclusion
The mass, velocity, density, gravity, inertia and size all affected how the ball/marble stayed on the track and how far it went. Being that we are not perfect the track was not 100% level but we did the best we could and I think this really was a fun project.
