» - » You must have a project design form signed by your science teacher before you begin your project. The project design form and this form must be returned with your project. Failure to return both forms will result in a penalty of 5%. If you begin your project before obtaining your science teacher's signature on the project design form, your project may be disqualified. » - » Check the TARGET GRADE (most likely your maximum grade) at the top of the page. » - » You may not use AC electricity to power your project. Only DC electricity of less than 5 amperes & 15 volts is permitted. » - » You may not copy another student's design for your project (except for bridges & towers). Yours must be significantly different. » - » You may not do the same project twice without permission from your science teacher. » - » In order to earn “bonus points” and extra credit, your project must be handed in by the due date, and must earn at least 96 %. » - » Projects handed in more than 4 days late will not be presented or tested in class. » - » You must complete a project design form and get it signed by your teacher before you begin your project. |
PROJECT GUIDELINES
1. Read
the INDEPENDENT PROJECT GENERAL GUIDELINES first.
2.
Complete a project design form
and get it signed by your science teacher.
3. Your
motor must have a power-on/power-off switch.
4. YOU
MAY NOT USE ALTERNATING CURRENT (A.C.).
5.
MAXIMUM OPERATING VOLTAGE FOR THIS PROJECT IS 15 VOLTS D.C.
6. If
you do not have a design of your own, obtain an instruction sheet from
your teacher for building the project.
7. YOU
MAY NOT USE A KIT, PREMANUFACTURED ELECTROMAGNETS OR COILS.
8. YOU
MAY NOT USE PERMANENT MAGNETS! All magnets must
be electromagnets constructed with magnet wire and iron or steel cores.
9. Demonstrate
the completed project to a class and explain the operation of the motor.
10. See the
Grading
Criteria for how you can earn an A+.*
Note 1:
20 gauge through 26 gauge magnet wire (available from Radio Shack®
stores and electric motor repair shops in the area) has been used successfully
in the construction of this project.
Note 2: Magnet
wire is insulated with a thin shellac or polymer coating instead of the
normal colored plastic insulation found on "bell" wire or automotive hookup
wire.
Note 3:BARE,
UNINSULATED WIRE WILL NOT WORK!!
