Lab  Take out your series circuit work sheet.  Find something to write with and a piece of paper for your group.  You will be grouped by row today.

Directions  Part 1  Measure the voltage of the battery.  Turn the dial to 20 on the multi-meter (top left)  Place one probe on the positive (+) and one probe on the negative (-) end.  Record the voltage.  Part 2  Measure the resistance of the resistors  Turn the dial to 20 (bottom left)  Place a probe on each side of the resistor  Record the resistance for each resistor (green, blue, and red)

Series Circuit Simulation  Re-create the circuit from question one and six from the series circuit work sheet.  Measure the voltage, resistance, and current in the circuit.  Compare the worksheet values to the simulations values and summarize your findings using academic vocabulary (measuring devices, voltage, resistance, current, etc.)

Parallel Circuit Simulation  Re-create the circuit from question five and six from the parallel circuit work sheet.  Measure the voltage, resistance, and current in the circuit.  Compare the worksheet values to the simulations values and summarize your findings using academic vocabulary (measuring devices, voltage, resistance, current, etc.)

Project  You will work in groups of three (groups larger than three need my approval).  The project is a test grade.  You can use any of the circuit supplies in the back to make your circuit. The only limitation is that it needs to fit on a circuit board.  You need to make a series and a parallel circuit (if you want to combine them and make a complex circuit you may do so).
