Electricity Presentation

Enjoy!

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!

Current ElectricityThis 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.

Examples of Current Electricity

These objects need to be plugged into an electrical outlet to work or charge.

Static ElectricityThis is electricity that collects on an object and

can cause a shock.

Lightning is a form of static electricity. Going down a slide

builds static electricity.

Balloons build static electricity easily. Rub one on your hair to make your hair

stand up!

Electrical ChargeThis 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).

+ _

+ +

ElectronA 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!

CircuitThis is a closed path that allows the flow of

electricity.

Circuits use current electricity to power

objects.

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.

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.

SwitchThis is a device that opens and closes a circuit.

A light switch is part of a circuit.

It could be as simple as a paperclip joining the

wires.

Move the paperclip to open the circuit.

ConductorThis 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?

Conductors

steelcopper

aluminum

More Conductors

gold iron

InsulatorThis 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?

Insulators

glass plastic rubber

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!
