Are there books you're supposed to have for your school work?  If not, instead of asking others to do your work for you, I would suggest getting a copy of "Heating, Ventilation, and Air Conditioning: A Residential and Light Commercial Text & Lab Book, 2nd Edition" and "Refrigeration & Air Conditioning Technology, 6th Edition".  Doing it for yourself is really the only way to learn.

I know a few:

Gas Valve - is located on the gas line into the furnace to cut off or on the flow of gas. Can be controlled by the thermostat opening and closing the valve. 

Pilot is the small flame/ light that stays on continuously to fire up the burner when it turns on.

Pilot Tube is the metal tubing that brings the gas to the pilot from the gas line.

A manifold is usually the thing that connects the motor to the exhaust venting.

I think some of those things are found on gas furnaces and others on electric furnaces.

I like ehow.com to find out stuff. Here are a couple of links:
