oneGTE-7B

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. Pre-read the lab up through Activity 1. 3. Flip your tag to GREEN once you

understand the setup.

Activity 2: Exploration

1. Close the switch again. 2. Observe the brightness of the

lamps.3. Open the switch. 4. Record your observations.

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.

Series Circuita. Bulbs connected one after the other.b. Bulbs are either all on or all off.
