Online Contest:
Erase A Chalkboard
Online Division I - Ages 11 - 14 (Middle School)
Team Leader: Mr. Stewart
Team Members: 7
Invitations: 0

What we're studying:
First we learned about the six simple machines: the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. Once we were comfortable with those machines we began to make more complex machines. Then, as a team, we started to brainstorm ideas for this years online competition.

Our Team Leader's favorite quote:
I do not think there is any that felt by the inventor as he sees some creation of the brain unfolding to success. - Nikola Tesla

Why we think we should win:
We used every simple machine - the lever, the wedge, the inclined plane, the wheel and the pulley. And we used screws to put it together!

Suggestion for next year's challenge:

Step 4. Pulley wheel travels down zipline carrying a ball that hits hit a baseball at top of inclined plane
Step 5. Baseball rolls down incline planes and sets off the newton’s cradle
Step 6. Newton's cradle hits baseball #2
Step 7. Baseball #2 falls into bucket #1 and pulls down one end of two buckets on a pulley system
Step 8. Pulley lifts bucket#2 which pulls a string which lifts a lever made out of a Jenga piece
Step 9. Lever releases a marble which rolls down a ramp made of hand-painted dominoes, paper cups, and popsicle sticks elevated by soup cans
Step 10. The marble hits the first in a series of dominoes of escalating size made out of computer cases
Step 11. The last and biggest computer case domino falls onto one end of a class 2 lever forming the lid of a student-made hand-painted box
Step 12. The lid lifts and releases a helium balloon, which is tied with other balloons to an eye screw in a brick
Step 13. The balloons pull the brick off a table
Step 14. A string attached to the brick pulls a pair of scissors closed
