Lab, Project Wednesday, February 24, 2016

Unit 9: Electricity Wednesday, 2/24 Look through your notes and write one question about the electricity unit you feel you need additional support (example – question four on the parallel practice worksheet). No questions? Then write about what you have found most challenging about this unit. Upcoming dates  Monday, 2/22 – Circuit design due- moved to Wednesday, 2/24  Wednesday, 2/24 – Unit quiz - moved to Friday moved to Friday, 2/26  Friday, 2/26 – Electricity Test and last day to turn in unit missing work – moved to Tuesday, 3/1  Thursday, 3/3 – Magnetism quiz – moved to Monday, 3/7  Friday, 3/4 – 3NWS Extra credit due by 4:00 PM  Friday, 3/11 – End of the 3NWS

Unit Reflection  Take out your series circuit, parallel circuit, and unit practice sheets from Thursday, 2/18 and Monday, 2/22.  Take a red pen and do the following;  Put a check mark next to the questions feel confident about.  Put a question mark next to the problems you are not quite sure about.  Put a ‘X’ next to the questions you have no idea where to start.

Review your self assessment with your group

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 200 (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).
