What we're studying:
We are studying how simple machines work together. Our team has also learned how to work together to accomplish a goal. Building our Rube Goldberg machine helped us learn how energy is transferred from one object to another.Our Team Leader's favorite quote:
Leave your area cleaner than you found it!
Our machine has a Route 66 theme. On road trips, we always remember to bring our snacks. One of our favorite road trip snacks are mini cereal boxes. We begin with a car that acts as a switch that turns on a motor that starts the journey onto Route 66 up a screw. The screw carries the car up the top of a mountain where it will descend down a series of different paths collecting our favorite cereal boxes. The Route includes inclined planes, wheels and axles, wedges, levers, motors and robots during our trip down the mountain. Our trip ends down a bridge to satisfy our hunger from such a fun trip, even our car cannot resist diving into a good bowl of cereal.
Our Step List
1. Push car down inclined plane to transfer energy to turn switch on surge protector. Surge protector powers the windshield wiper motor to be on.
2. Small ball attached to screw (which is attached to motor) travels upward on a screw.
3. The small ball is released at the top of the screw, which transfers energy to a domino effect.
4. Final domino hits golf ball to travel down various inclined planes.
5. Golf ball lands in a cup which drops down on a pulley, causing the cup on the other side of the pulley to be pulled upward, exposing light to the light sensor on the Makerbot.
6. Makerbot (precoded to respond to light) moves forward for 4 seconds at the sensing of light, pulling a stop off an inclined plane.
7. The released stop allows a car to travels down an inclined plane, hitting a lever to release a second car.
8. The second car is released down an inclined plane to hit a block, which is tied to another block sitting atop a beam.
9. The other block pulls a stop down.
10. The released stop allows the third and final car to travel down an inclined plane.
11. A wedge attached to the final car pops a balloon filled with cereal over an empty bowl, filling the bowl with cereal.
