Rube Goldburg Science Project 2020

For this assignment we had to create an obstacle coarse that would show how to complete a task of our choice. We chose to get a marble into a hole as our task. Our coarse went throughout the counter down onto a lower table, and then onto the floor. We had 3 levels of a coarse. Our coarse we started by using a piece of food to bump the piece down the incline to hit jingo pieces until a marble fell through the tunnel. Then it reached the 2nd level which knocked down another row of jenga knocking a marble into a hat which made the folder open up. That knocked over another large row of jenga up another incline to knock a larger marble into the last hole. Once the marble was knocked over that was the end of our task.

We also had 4 energy transformations in our project which were: 

Chemical to mechanical

mechanical to mechanical

mechanical to sound

mechanical to gravitational. 

3 simple machines:

incline plane

screw and

wheel and axle.
