Unit 2 Test: Energy Transfer2

The image shows a simple circuit.

To close the circuit and turn on the light bulb, what needs to be done?

• Attach a magnet to the battery to complete the circuit.

  
  

• Push the switch all of the way down to complete the circuit.

• Add another battery to complete the circuit.

• Attach another wire from the battery to the switch to complete the circuit.

Electrical Circuits

Students in a 4^th grade science class were investigating electrical circuits. The teacher put a box of wires, bulbs, and batteries on each table. The students’ assignment was to explore energy using the wires, bulbs, and batteries. They created the simple circuit below. It has a battery, a switch and a light bulb. They noticed that if the switch is open, the electricity will not flow through it. If the switch is closed, the electricity will flow through the circuit.

Which evidence shows that energy is being transferred from one place to another?

• When you can see the electricity traveling through the wires

• When you can see sparks coming from the battery

• When you can see the switch open

• When you can see the light bulb light up
