Why are electrical wires covered in plastic?

Plastic is a good insulator so you won't get shocked.

100

What is the area around a magnet where the magnet's force reaches called?

Magnetic Field

100
A type of energy in which small particles (electrons) move through a device.
What is electricity?
100

We tested various materials like popsicle sticks, yarn, paperclips, foil and wire mesh in this experiment.

What is testing items to be conductor and insulator?

100
Anything an electrical current can pass through easily.
What is conductor?
200

Materials you should never stick in a plug in.

What are conductors (such as metal)?

200
This happens when you put the north pole of one magnet towards the south pole of another magnet.
What is they attract?
200
Where the current flows from the battery through an electrical device providing power, and returning back to the battery.
What is a closed circuit?
200

When we created a _________________ circuit using conductors, the light bulb lit up.

Closed

200
A path for an electric current.
What is a circuit?
300
You should never use this while taking a bath.
What are anything that is plugged in (for example a radio)?
300
Name a type of metal that can be magnetized?
What is iron or nickle?
300

Electrons from the hair build on a hat so your hair stands up because it is positively charged.  This is called _______________________.

Static Electricity

300

This was the independent variable in our circuit building experiment.

The different materials used in the circuit

300
A flow of electricity.
What is a current?
400

You should not carry one of these during a storm.

What is an umbrella?

400
The 3 things you need to make an electromagnet.
What are a battery, wire and iron nail?
400

What type of energy transformation takes place in an oven?

Electrical to thermal

400

We used symbols to show this in our insulator and conductor experiment.

A circuit

400
Materials that electricity has a hard time flowing through; for example plastic, leather or wood.
What is an insulator?
500

You should not do this outdoor summer activity at the beach during a storm.

What is swim or take a boat ride?

500

This can increase the strength of an electromagnet made with a battery, wire and iron nail.

Wrap more wire coils around the nail

500

A large discharge of static electricity seen during storms.

What is lightning?

500

This was the dependent variable in our insulator/conductor experiment.

The light bulb lighting up

500

An electrical component which slows electron flow.

What is a resistor?
