What we're studying:
We have studied measurements, angles, and educated guessing (if that counts). We have also learned about how electricity works and wiring, and how to create an electrical circuit that works. Last year, I did a rube goldberg machine in my science class, so I have just a little bit of experience with how things move. This year our teacher says we will use them to learn about forces and motion and how energy is transferred from one object to another.

Our Team Leader's favorite quote:
"Life doesn't require that we be the best, only that we try our best." By H. Jackson Brown Jr (author of Life's Little Instruction Book and P.S. I Love You)

Why we think we should win:
I think we should win because we have been trying and doing our best since we started the Rube Goldberg. We have had fun doing it. We've had very hard thinking moments, but always get through them as a team. When we started, none of us knew each other, so I believe that getting through our challenges as a team is a good thing. We have all worked very hard. I honestly would like to win because we have actually put effort and time into this, and I really think that we have all been dedicated.

Suggestion for next year's challenge:
Bake a pop tart
Turn on a computer



Books, books, books...and creativity, of course! Our teammates' love of books sparked inspiration early on in our building process. They provided the initial ideas for what would become some of our steps and provide actual support for most of our machine. Hesperia Junior High yearbooks actually act as a step in our machine combining Roadrunner pride and Rube Goldberg creativity. Ask a reader about the books they love, and they end up talking about more than just the book. Pouring cereal, yes, but with our Rube Goldberg machine, it's so much more (and magically delicious)!

Our Step List

1. Narrator opens the book
2. Book cover flips a light switch
3. Light switch activates a fan
4. Fan blows over a book
5. Book activates a mouse trap
8. Activated mouse trap, pulls the stick which is holding a ball from rolling down a ramp
9. Ball rolls down ramp, hits the wall which changes its direction, and rolls down another ramp
10. Ball knocks a book down which knocks other books down in domino effect
11. Book falls onto a lever
12. Rope attached to the lever turns on a light
13. Light burns the yarn which simultaneously activates a pulley which lowers a stack of magnets onto magnets attached to the cover of a book and... go to step 14
14. pulls a popsicle stick holding back 2 ball bearings from rolling down a ramp
15. Ball bearings roll down a ramp where the weight pushes and activates a switch (with the help of a magnet on the back end of the switch to increase the force on the switch)
16. The switch completes an electrical circuit which powers a second motor acting as a wheel and axle
17. As the axle spins, it winds up a rope connected to a second pulley which lifts the magnets that were connected in Step 13.
18. As the magnets attached to the book cover are raised, the book cover opens creating an inclined plane on which the cereal container rests.
19. Height and angle are achieved to unbalance the forces acting on the resting cereal and cause it to pour.
