Energy Lab Worksheet Part 1: Rube Goldberg Interactive 

Use the interactive version of a Rube Goldberg machine in the lesson. Fix the device so the flow of energy is not interrupted, and the window shade can be closed.

Give three examples, from the lab, where potential energy was converted to kinetic energy.
The ball is pushed from the Newton's cradle 
The crayons they fell and they have potential energy into kinetic energy 
The balls are seesaw and it converted to potential energy to kinetic energy when it was in the air.
Describe the five adjustments you made to the Rube Goldberg device in order to keep the flow of energy going.
The bucket to the rope 
To moved the seesaw with the ball
Put together the ball and the sling shot 
Moved the self to a different places 
Add 5lbs to the other shelf 
What was a constraint (a limitation or a condition) in this version?
it would work perfectly when all of it are adjusted but we're made in real life even if everything is in the perfect places.
