Electricity for elementary

1. Electricity

2. Electricity
Think:
Can you think of anything that
uses electricity?

3. Electricity is Everywhere
• In your home, electricity runs the
lights, television, toaster, machines,
heats, and does much more. It’s hard
to even imagine what your life would
be like without it.
• What is electricity?

4. Energy
• Electricity is another kind of energy.
• It travels through wires to your home.
• We will learn about two types of
electricity: current electricity and static
electricity.
• Current electricity goes from one
place to another.
• Static electricity stays in one place.

5. This is Current Electricity
2. The power plant
sends electricity
through power lines.
Overhead power lines
carry electricity to
transformers on poles.
3. From transformers,
electricity travels into
houses and buildings
through wires.
1. Electricity travels in
a circuit that begins at
a power plant.
4. Electricity flows from the
wires in the wall to the outlet,
then to the appliance cord.
5. When you plug
something in and turn
it on you complete
electricity’s circuit.
Current electricity goes from one place to another.

6. Batteries
• People also get electric energy from batteries.
• We use batteries to get electricity into objects
that are not connected to a wall plug.
• This electric energy is used for many things.
– toys
– radios
– cameras
– flashlights
– watches
– cars

7. Complete Circuit
• In order for electricity to travel to
where we need it, there must be a
complete circuit of electricity. A
complete circuit is like a circle.
• A circuit is a closed path so
electricity can follow.
• Electricity starts at a particular
place, travels around the circuit,
and returns to the same place.
• No circuit will work if it has a
break in it.

9. What is static electricity?
• You walk across the rug, reach for the
doorknob and..........ZAP!!! You get a shock.
Or, you come inside from the cold, pull off your
hat and......BOING!!! All your hair stands on
end. What is going on here? And why does it
only happen in the winter?
The answer is: STATIC ELECTRICITY

10. Static Electricity
• Static electricity stays in one place.
• Rubbing an inflated balloon on clothing or
rubbing your shoes on carpeting forms
static electricity.
• This happens because tiny particles
called electrons move from one object
to another. These particles have a
negative charge.
• Static electricity is created when an
object gives up or gains these electrons.

11. Benjamin Franklin
1706 - 1790
• Benjamin Franklin was
known as the “Electric
Man”.
• He was the first scientist
who experimented with
lightning and electricity.
• Electricity is one of our
most widely used forms
of energy. Benjamin Franklin Memorial
Philadelphia, Pennsylvania

12. Electricity Moves Fast!
• Electricity travels at the speed of light. At
186,000 miles per second, it gives you no
time to react! You can’t move faster than
electricity, so you just have to stay out of
its way.

13. Safety Tips
• Never play with electrical cords, wires, switches, or plugs.
• Stay away from fallen power lines. Tell an adult if you see
a fallen line.
• Never use a hairdryer or play an electrical radio or
television near a bathtub or sink.
• Before you climb a tree, look up. If a power line is nearby
or touching, stay away from the tree.
• Never touch anything that runs on electricity when your
hands are wet.
• Fly kites and model airplanes in a wide open field or park
—never near overhead electrical wires.
• Never climb utility poles or electrical towers.
• Stay away from substations and transformers
(green boxes).

14. Congratulations!
• You have learned the difference
between current electricity and
static electricity.
