Enjoy!

2. Electricity is at work all around you!
Look around your classroom. Predict which objects are using electricity right now.
Let’s look at some different types of electricity!

3. This is electricity that flows from one place to another.
Current Electricity
This is electricity that flows from one place to another.
Many examples of current electricity are easy to spot because they use cords/wires plugged into an outlet in the wall.

4. Examples of Current Electricity
These objects need to be plugged into an electrical outlet to work or charge.

5. Static Electricity
This is electricity that collects on an object and can cause a shock.
Balloons build static electricity easily. Rub one on your hair to make your hair stand up!
Lightning is a form of static electricity.
Going down a slide builds static electricity.

6. This is the amount of positive or negative electricity in an object.
Electrical Charge
This is the amount of positive or negative electricity in an object.
This is difficult to understand because it involves protons, neutrons, and electrons which are so tiny we can’t see them! _ + + +
Positively charged particles attract negative charges because opposites attract! Two like charges repel (push away).

7. Electron A small particle that carries a negative charge.
Electrons travel around the nucleus (center) of atoms.
There can be over a million atoms on the head of one pin!

8. Circuit This is a closed path that allows the flow of electricity.
Circuits use current electricity to power objects.

9. How can I make a circuit?
A simple circuit can be made with a battery, 2 wires, and a light bulb in a bulb holder.

10. How can I make a circuit?
Connect the wires to each end of the battery and on both sides of the light bulb holder to make a complete path for the electricity to travel through.

11. Switch This is a device that opens and closes a circuit.
It could be as simple as a paperclip joining the wires.
A light switch is part of a circuit.
Move the paperclip to open the circuit.

12. Conductor This is a material through which electrons can move easily.
This means that electricity can flow through an object.
Do you know what these objects are made of?

13. Conductors
aluminum
copper
steel

14. More Conductors
gold
iron

15. Insulator
This is a material through which electrons cannot move easily.
This means that electricity cannot flow through an object.
Do you know what these objects are made of?

16. Insulators
plastic
glass
rubber

17. Examples of electricity can be found almost anywhere you look!
See how many examples you can identify in your classroom, at home, or the next time you are out!
