oneEEM-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.

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.

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

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