A student turns on a computer to do homework. He then walks across the carpet and touches the metal chair to see a flash of light and feel a shock. Which statement is the best explanation of what was observed?

Both actions are examples of electricity. The computer is powered by current electricity and the shock is caused by static electricity.

The computer is the only example of electricity. It is plugged into the wall and is powered by current electricity.

The shock is caused by static forces and it is not plugged into the wall so it could not be electricity.

The shock and flash of light was caused by current electricity from the computer. There is no static electricity in the room.

A teacher gave the class the following list of items and asked the class to determine if the item is an insulator or a conductor of electricity. paper clip water bottle cap black paper aluminum foil penny eraser shoe lace How could the students prove their answers through an investigation?

Create a circuit with a lightbulb and then replace one of the wires with the item. If the lightbulb turns on, then it is a conductor if the bulb does not light it is an insulator.

Put the objects in the sun. If the item becomes hot, it is a conductor of electricity and if the item is the same temperature then it is an insulator.

If the item is hard and shiny it’s a conductor, if the item is soft or flexible it is an insulator.

Touch each object with a battery to see if it will produce a spark, if it does then it is a conductor, if it does not then it is an insulator.

A student notices that when the fire alarms at the school go off, the doors close with the alarm and when the student tries to reconnect the door to the magnet behind the door, it will not attract. Which of the following arguments BEST describes the type of magnet the student is observing.

The magnet is a temporary magnet because the fire alarm is connected to the circuit of the door. The magnet is currently turned off.

The magnet is a temporary magnet because the fire alarm is connected to the circuit of the door. The magnet is currently turned on.

The magnet is a permanent magnet because the fire alarm is connected to the circuit of the door. The magnet is always turned off.

The magnet is a permanent magnet because the fire alarm is connected to the circuit of the door. The magnet is always turned on.

A fifth grade student put a strong magnet in a plastic cup. He then put the cup with the magnet into a wood box on his desk. To his surprise, stray staples and paper clips were attracted to the magnet in the box. What statement best describes what the student observed?

Magnetic fields pass through many materials. There is no material that will block magnetism.

Magnetism can be strengthened by conductors.

Magnetism does not go through other non-metals.

Magnetic forces only attract iron.

A student is investigating whether the magnetic field of magnets is affected by different materials. The student followed the following steps. 1. Place 20 paperclips on the table. 2. Wrap a piece of paper around the magnet 3. Slowly lower the magnet towards the paperclips Which of the following steps should the student take in their investigation?

Step 4: Count the number of paperclips attracted to the magnet, and then remove paperclips on the magnet. Step 5: Repeat steps 1-3 using cotton fabric, cardboard, and plastic wrap.

Step 4: Repeat steps 1-3 using cotton fabric, cardboard, and plastic wrap. Step 5: Count the total amount of paper clips from the investigation.

Step 4: Count the number of magnets attracted to the magnet, and then remove paperclips on the magnet. Step 5: Repeat steps 1-3 using cardboard, a metal sheet, and plastic wrap

Step 4: Count the number of magnets attracted to the magnet, and then remove paperclips on the magnet. Step 5: Remove the magnet and try to pick up paper clips using a metal sheet.
