•  Electronics Unit

    In this unit, students explore electricity and electronics, the foundation for much of the technology in our world. 

    In the first activity, students use Snap Circuit electronic training kits.

    The circuits allow students to quickly, easily and safely build a variety of circuits.  Students learn about and experiment with concepts such as: 

    • conductors and insulators
    • voltage,current and resistance
    • series and parallel circuits
    • how various components function in a circuit 
    • schematic symbols
    • polarity
    • short circuits
    • troubleshooting

    In the second activity, each student will make their own L.E.D. flashlight.  

    To make the circuit, students:

    1. Fabricate a circuit board.

    4. Use a multimeter to perform voltage, resistance and continuity tests.


    5. Troubleshoot and repair any circuit problems.

    6. Manufacture a protective housing for the circuit from a recycled container.
