Electricity & Electronics Middle School Challenge
Program Overview In the Electricity & Electronics Middle School Challenge there are a series of investigations that explore series and parallel circuits, Ohm's Law, Lenz's law, magnetism, with an introduction to electronics. Student teams construct circuits on breadboards using resistors, capacitors, transistors, jumper wires, a group power supply, LEDs, switches, loudspeakers, and photo cells. These experiments introduce the basic circuits that are behind most of our modern electronics as they build circuits' e.g. light dimmer, light sensor, polarity detector, switch dimmer, and how the volume of a buzzer in a circuit is affected by different voltage. They investigate the relationship of electricity to magnetism by building a solenoid switch, galvanometer, electric motor, construct and demonstrate a circuit in oscillation that will keep flashing as long as the battery is connected and the components keep working, and construct and demonstrate a circuit that is in essence a switch.
