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!
