1. oneone EEM-8C Objective: To explore series circuits in order to see how circuits transfer electricity Energy Note: How do circuits differ from each other?? Drill: 1. Get a new lab from the SET. 2. Form teams and get your team tag. 3. Each group needs a materials tote and BOTH circuit boards. 4. Compare your homework diagrams. 5. Wait quietly for directions.

2. oneone EEM-8C HOMEWORK CHECK

3. oneone EEM-8C Materials: Parallel Circuit Board (1) Switch (1) D-Cells in Holders (2) Wires (5)

4. oneone EEM-8C DO NOT LEAVE THE SWITCH IN ANY CIRCUIT CLOSED FOR A LONG PERIOD OF TIME.

5. oneone EEM-8C Activity 1: Construction Construct the circuit shown Figure 2. Figure 2 Example Circuit 1 A B C D E F Close the switch to test the circuit.

6. oneone EEM-8C Activity 2: Exploration 1.Close the switch again. 2.Observe the brightness of the lamps. 3.Open the switch. 4.Record your observations. Compare to the previous circuit.

7. oneone EEM-8C 1.Close the switch and remove one of the lamps from its base. 2.Record your observations. Why do you think this occurred?

8. oneone EEM-8C 1.Identify the type of circuit you have constructed. 2.Justify your response with information from the lesson and your observations. Parallel Circuit a. Each bulb is on a different branch. b. When one bulb goes off the rest stay on.

9. oneone EEM-8C Close the switch. Connect a wire from connection B to connection D. What happens? Why do you think this occurs?
