Challenge
Your task is to prepare a kit of materials and instructions that the toy company will manufacture. Children will use these kits to make a motor or generator, or a combination electric motor/generator. It will serve both as a toy and to illustrate how the electric motors in home appliances work or how electricity can be produced from an energy source such as wind, moving water, a falling weight, or some other external source.  |

Criteria
Your work will be judged by the following criteria:
- (30%) The motor/generator is made from inexpensive, common materials, and the working parts are exposed but with due consideration for safety.
- (40%) The instructions for the children clearly explain how to assemble and operate the motor/generator device,
and explain how and why it works in
terms of basic principles of physics.
- (30%) If used as a motor, the device will operate using a maximum of
four 1.5-V (volt) batteries (D cells),
and will power a toy (such as a car, boat, crane, etc.) that will be fascinating to children.
OR
- (30%) If used as a generator,
the device will demonstrate the production of electricity from
an energy source such as wind,
moving water, a falling weight,
or some other external source
and be fascinating to children.
