Review for:Beakman's Electric MotorIf you used this resource in your own classroom, please add your review. posted: on June 1, 2007 at 9:17AM
My rating of this resource: ****
My experience using this resource: physics
Topic I was teaching: electricity and magnetism
My learning goal for which this resource was used: to have students understand the operating principles behind a DC motor, including direction of force on a wire, torque on current-carrying loop, magnetic field produced by a wire loop, and the way a commutator functions in a DC motor
Course Level: Honors or Advanced, Intro or Regular, Remedial
How I/my students used the resource: I printed out the instructions from the web site and students used the instructions to build their own DC motor in small groups
Value Added: Provides practice or tutorial, Provides additional content, Increases student engagement and motivation
Strengths: instructions are clear and easy to follow, materials are inexpensive and easy to acquire, students get a kinesthetic feel for the forces involved
Weaknesses: might be seen as too "juvenile" by advanced students?
