As Eric said in his blog, in FE8B we are also making a Rube Goldberg machine. Today we came up with the main plan as a class and starting next Science class we will start constructing the machine. Our plan went something like this:
1. the ball is in a car (wheel and axle) that goes down an inclined plane
2. the car hits a wedge and stops, but the momentum flings the ball out
3. there is a pulley balancing with a cup at one end and a weight at the other and the ball lands in the cup, moving the cup downwards
4. the cup lands on a 1st class lever and tips over, rolling the ball into a cup on the other end of the lever
5. the cup goes back up the pulley as it is now lighter than the weight on the other end of the pulley
6. the weight comes down and hits the end of the lever to launch the ball
7. the ball lands in a funnel and goes around and around (like a screw) and then into a tube
8. the tube shoots the ball out to hit a 3rd class lever that spins around in a circle, hitting the handle on a driver gear on its way
9. the lever comes back and hits the ball onto the gear train that would be already moving
10. the ball would ride along the gear train that looks kind of like a bike chain and gears as there is a driver gear at one end and a slave gear at the other, connected by a chain
11. the ball will have moved accross the room and into the bucket!
I know it sounds confusing, but I think we can make it work. It seems like fun, if anything.
Until next Wednesday,

P.S. I just wanted to put it out there that its not supposed to SNOW in OCTOBER!!!!!!!!!! I'm not ready for Winter yet!... :(
