- Voltage, Electric Energy, and Capacitors: Crash Course Physics #27 (Electric Charge – YouTube)
- Electric Current: Crash Course Physics #28 (Electric Charge – YouTube)
- DE Resistors & Batteries: Crash Course Physics #29 (Electric Charge – YouTube)
- Circuit Analysis: Crash Course Physics #30 (Electric Charge – YouTube)
Have the students take out their SeaPerch Construction Manuals. Focus the students’ attention on the “Assembly of the Control Box” section of the manual.
Explain the process for electrical system construction and soldering. Make sure that the students know to follow the correct order when adding components to the circuit board, or it will become difficult to solder pieces on the board.
While the other students are working on the other SeaPerch systems, help the electrical engineers to create their control box for their ROV. Students should visually inspect their soldering to ensure there are no short circuits, and should conduct a continuity test with an Ohmmeter or digital multimeter.
