THE ELECTRIC POWERED VEHICLE
OBJECTIVE:
To learn that the scientific method is not a linear process.
To learn the difference between potential and kinetic energy. To learn to use different forces of prime movers; mechanical, fluid, electrical, heat, chemical.
To learn the principles of forces like compression, torsion, strain, and shear.
Learn the principles of friction.
Learn the basics of circuitry and how to solder.
To work independently or cooperatively. To learn to brainstorm (lens smashing) and develop problem solving skills. Make decisions using trial and error. Work within a given amount of time. Work with only materials given. Deal with competition with your peers.
PROBLEM:
Given the materials from the KELVIN Hovercraft kit along with additional materials, construct a vehicle powered by an electric motor.
GIVEN:

Access to other resource materials
Soldering iron
Solder, flux etc.
Hot glue melt
Access to limited power tools and equipment.
LIMITATIONS:
The vehicle must be self contained.
The vehicle must be built to scale and in proportion. At the discretion of the instructor.
The capacitor on the electrical mechanics may be replaced with a AA or AAA battery.
Reduction gears and assemblies may be designed. (gearbox from KELVIN).
Student may bring their own resource materials and parts.
No explosives or other dangerous items allowed.
Power tool use will be monitored at the discretion of the instructor.
EVALUATION:
Students will test their own vehicles.
The instructor will be the official assessment recorder.
Vehicles will be tested on a flat smooth surface.
A large open area such as the gymnasium.
