Let students carefully take apart one or more old DC motors. Point out the different components of the motor and have them identify each part (see below). Discuss how motors work and the energy transfer that occurs.
a. Armature
b. Permanent magnet
c. Brushes
d. Casing
Show students this short video of how an electric motor works. This will show students how electric energy is turned into motion (spinning) using an electromagnet.

Have the students take out their SeaPerch Construction Manuals. Focus the students’ attention on the “Assembly of Mechanical System” section of the manual.
Show the students the motors they will be using for their SeaPerch ROVs. Explain the process for the mechanical system, including waterproofing the motor with wax and creating the CAT5 cable. Before students begin work on their mechanical systems, the teacher should demonstrate the proper use of a soldering iron.
