Electricity & Magnetism Test

A student tested these items to see if they were conductors or insulators: penny (insulator), paper (insulator), toothpick (insulator), metal paper clip (conductor), metal nail (conductor). What is the best claim I can make from this data?

• Metal is a conductor.

• Nails are an insulator.

• Toothpicks are conductors.

• Metal is an insulator.

A student built an electromagnet with a nail, wire, and battery. Which of the following will most likely to make this electromagnet stronger?

• Using less coils (wire wraps).

• Remove the nail.

• Add another battery.

• Remove the wire.

Your mom puts a pot of water on the stove. It gets hot and starts to boil. What most likely happened to explain this?

• Electric energy changed to heat energy.

• Heat energy changed to water energy.

• Electric energy changed to gas energy.

• Heat energy changed to a gas energy.

A student uses a metal paperclip to complete a circuit. The light bulb lights up! What is the best claim that can be made from this evidence?

• The paper clip is an insulator.

• The paper clip is a conductor.

When the switch in the circuit model was turned "on", the light bulb lit up. What is the best explanation of why flipping the switch caused the bulb to light up?

•  It completed the circuit which allowed the chemical energy from the battery to reach the bulb.

• It did not complete the circuit which allowed light energy from the battery to reach the bulb.

Sally drew this picture to show how a magnet attracts nails. Why did she most likely draw the nails where she did?

• Magnets repel nails at the poles.

• Magnets repel nails in the middle.

• Magnets are stronger in the middle.

• Magnets are stronger at the poles.

Sally built an electromagnet with a nail, wire, and a battery. It was able to pick up paper clips. Explain why this happened.

• It creates energy.

• It creates electricity.

• It creates heat.

• It creates a magnetic field.

A student tested 4 electromagnets. Which one would be the strongest?

• 1 battery, one nail, and 10 coils (wire wraps).

• 3 batteries, one nail, and 10 coils (wire wraps).

• Two batteries, one nail, and 20 coils (wire wraps).

• Three batteries, one nail, and 20 coils (wire wraps).

Sam felt hot one summer day.  He plugged in a fan and turned it on.  The fan blew the air and cooled him off. How did the fan make the air move?

• Heat energy transformed into cool energy.

• Heat energy transformed into wind energy.

• Electric energy transformed into energy of motion.

• Electric energy transformed into cool energy.
