Carolina STEM Challenge®: Motors Kit

$95.80

Product: (in stock)

Description

Students investigate how electric motors use electric and magnetic interactions to convert electrical energy to kinetic energy and address the engineering problem, "What changes can be made to make a simple motor spin faster?" Design teams are guided to build and test a simple electromagnetic motor prototype. During the Design Challenge, teams brainstorm ways to modify the motor design, performing trade-offs and adjusting parameters to maximize the revolutions per minute of the wire coil. Design teams build new motors to improve performance, incorporating ideas from brainstorming. The activity concludes with a classroom competition of their engineered motors.

Learning Objectives

  • Apply principles of electromagnetism to design, build, and evaluate a simple electric motor.
  • Refine and optimize the performance of the electric motor to maximize its rpm, varying parameters.
  • Learn and practice the engineering cycle to meet specific performance criteria.
  • Communicate ideas about the process, design, and results in a clear, coherent presentation.

Prerequisite Knowledge and Skills
Prior knowledge of magnets, magnetic fields, electromagnets, electric motors, and energy transformations are useful.

WARNING: Neodymium magnets have a very strong magnetic field. Use with caution. Seek immediate medical attention if magnet is swallowed.
