5th Grade Unit 4 Energy Formative Assessment

Richard designed an experiment to test different materials to determine if they were an insulator or a conductor. He tested a wooden popsicle stick, a plastic spoon, a metal spoon, and an eraser. He set up a simple circuit connecting a battery to a light bulb with a small gap. One at a time he connected the circuit with the chosen test materials and recorded whether the light bulb came on. Based on what you know about electrical conductors, which material made the bulb shine?

• The wooden popsicle stick

• A plastic spoon

• A metal spoon

• An eraser

Pam’s teacher asked her group to design a simple electric circuit. What materials would be necessary for Sam and her group to complete a simple circuit to turn on a bulb?

• Battery, wire, and bulb

• Battery and bulb

• Wire, bulb, and switch

• Battery, wire, and switch

Which of the following is an example of human-harnessed electricity? S5P2a

• Lightning striking a building

• Getting a small shock when touching a doorknob

• A hydroelectric dam

• Socks sticking together in a dryer

The diagram below shows an electrical circuit with a buzzer. The students noticed that the buzzer was not making any sounds. What could be done to make this buzzer work?

• add another battery to the circuit

• Replace the buzzer with a light bulb

• Switch the wires to make a better connect

• Close the switch to make a complete circuit

Based on your knowledge of electromagnets and permanent magnets, why would cranes in a junk yard use an electromagnet instead of a permanent magnet?

• Because an electromagnet is always stronger than a permanent magnet

• Because an electromagnet is always weaker than a permanent magnet

• Because only the electromagnet attracts metal

• Because the electromagnet can be turned on and off

The image below shows a magnet with iron filings on a piece of paper. Where is the magnetic field the strongest?

• The magnetic fields are the strongest in the middle of the magnet.

• The magnetic fields are the strongest under water.

• The magnetic fields are strongest at the poles.

• The magnetic fields only have strength at night.

Students are investigating to see if magnets will attract objects through different materials. They observe that the setup shown below works and that the magnet attracts the object. The object will most likely still be attracted to the magnet if which of the following changes occur?

• The magnet is moved much farther away from the glass.

• The glass is replaced by a piece of paper.

• The nail is replaced with a plastic spoon.

• The glass is replaced with a thick piece of wood.

Use the lines provided explain how a light switch works and why you do not get shocked when touching the switch.

• A light switch works by completing or breaking an electrical circuit, and you do not get shocked because the switch is insulated.

• A light switch works by generating electricity, and you do not get shocked because it is made of rubber.

• A light switch works by storing electricity, and you do not get shocked because it is grounded.

• A light switch works by converting electricity to light, and you do not get shocked because it is waterproof.
