5.6b

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

• Light bulb 1 and light bulb 2 will both be on

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off

Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 3 is closed and the other switches are left open?

• Only the white bulb will operate

• None of the bulbs will operate

• Only the white and yellow bulbs will operate

• Only the red and blue bulbs will operate

The circuit has 3 lightbulbs and a bell. Which procedure will result in only the blue lightbulbs operating?

• Close switches 1 and 2 and leave switch 3 open

• Close switch 3 and leave switches 1 and 2 open

• Close switches 2 and 3 and leave switch 1 open

• Close switch 2 and leave switches 1 and 3 open

When a circuit is open, the circuit is _________?

• On

• Off

In the picture, if you replace the paper clip with a plastic spoon, what happens? 

• The bulb doesn't light
• The bulb is dimmer
• The wires get hot
• There is no charge

Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper conducts electricity

• Because copper is not magnetic

• Because copper insulates electricity

If no changes are made to this circuit, what will the results be?

• Both bulbs are off because the switch is open

• Only the left bulb is lit because it has a closed path. The right bulb is not lit because of the open switch

• Both bulbs are lit because they each have a complete, closed path to the battery

• Only the right bulb is lit because an open switch causes the energy to flow to the bulb.

A fifth grade class constructed this circuit.  Which of these objects most likely made the light glow when connected to points X and Y?

• plastic straw
• cotton string
• aluminum foil
• rubber eraser

Which light will be brighter and why?

• Bulb A because its circuit is closed
• Bulb B because its circuit is closed
• Bulb B because it has more volts
• Bulb A because it has less volts

Look at the four ways that you could connect a battery, a paper clip, a light bulb, and some wire.

Which one of these would light the bulb?

• 
• 
• 
•
