Introduction #1 Circuits have devices that use _________________ energy, such as a light bulb.

• nuclear
• electromagnetic
• thermal
• electrical

Introduction #2 Circuits have a source of electrical energy, such as a _____________.

• lightbulb
• battery
• fan
• resistor

Introduction #3 Electric circuits are connected by conducting ______ that complete the path of the electric current.

• wood
• plastic
• wire
• resistors

Layout #1 Compare the brightness of the bulb in the 1st circuit you built to the 3rd circuit you built with 2 bulbs.

• 1 bulb shines brighter than 2 bulbs in a series circuit
• 2 bulbs shines brighter than 1 bulb in a series circuit
• 1 bulb and 2 bulbs shine with the same brightness

Layout #1 What type of circuit did you build?

• series
• parallel

Layout #1 What happens when the switch is open in circuit 2?

• The light turns on 
• The light turns off

Layout #1 Did the bulbs light in the fourth circuit you built Explain

• No, because the switch is open.
• No, because the broken light bulb makes the circuit incomplete. 
• Yes, because they are connected in series.
