Kinetic Sign Design
A. The Driver Gear will be controlled by a hidden motor behind the sign. This will then turn all the other gears.
B. A rod will be connected from a gear to a push button switch which is meant to turn lights behind the element boxes on and off. The two elements where chosen to represent Mahtomedi's school colors, blue and gold.
C. A rod will be connected from a gear to the green box which will move it up and down the incline plane. This is meant to represent the concepts of force and simple machines.
D. A rod will be connect from a gear to a white sphere that will move horizontally. This is meant to represent a water molecule forming hydrogen and hydroxide ions.
E. A rod will be connected from a gear to a 1st class lever; the lever is then connected to a flower that will move up and down, representing plant growth.
F. A rod will be connected from a gear to a car causing it to move back and forth. Below the car is a graph that will represent the motion of the car.
G. Finally, a digital count will display the total rotations completed by the driver gear and the number of rotations per minute so students can calculate total run time.
