Grade 5 Electricity Quiz

Lee thinks that she has a break in her circuit because her light bulb will not glow. She thinks that a break can only be at the beginning of the circuit. Dan knows that she is wrong. He tells her that a break can be

• outside of the circuit.

• inside the battery.

• anywhere in the circuit.

• next to the light bulb.

Lightning can be best described by which statement?

• The flow of light between the cloud and the ground.

• The movement of air between the clouds and the ground.

• The movement of sound between the clouds and the ground.

• The flow of electrical charges between the cloud and the ground.

What will create static electricity?

• wrapping wire around iron and sending a charge through the wire

• flipping on a light switch in your classroom

• allowing like forces to attract (negative attracts negative)

• rubbing a balloon against your hair

Electricians wear rubber gloves when working with electric lines. Explain why Electricians wear rubber gloves when working.

A student took a working bulb and wire from an existing circuit and built a simple circuit but the bulb did not glow. What is a possible explanation?

• The bulb is too big

• The bulb does not work

• The wire is too short

• The battery has no charge

A student is trying to make a simple circuit he gathers the following materials: a battery and a lightbulb. Could the student create a simple circuit using only these materials?

• No, because the student needs a wire for the electric current

• No, because the student is not a wizard.

• Yes, because there is a load and a power source

• Yes, because there is a current and a power source

The diagram shows an electric circuit a student plans to build. When the Student connects the wires as shown, which bulbs will light? (Left, middle, or right?) Be sure to explain!

Some strands of lights use a circuit where one burned out bulb will keep all the other bulbs from lighting. Which Circuit would allow the other bulbs to stay lit if a bulb burned out?

• D

• C

• B

• A

Which material is a good conductor of electricity?

• plastic

• rubber

• wood

• copper

Identify number #11 in the photo.

• Opens and closes the circuit

• Power source

• Load

• The electrical path/conductor
