What is Energy?

• Energy is everywhere, and we use energy every day!

• Energy allows us to do work.• It can change or move matter.

Do you use energy when you play soccer or make cookies?

©FoodForTaught

Kinds of Energy• The kinds of energy we will

be learning about are:

©FoodForTaught

1. Heat2. Electricity3. Sound4. Light

Heat from the SunHeat is a kind of energy that can make

objects warmer.

©FoodForTaught

• Most heat comes from the Sun. • The Sun warms the Earth’s air,

land, and water.

• How do you think heat would affect an ice cube if you left it outside?

Heat from FuelHeat comes from other things besides

the sun too.

©FoodForTaught

• Fuel is something that gives off heat when it burns.

• Gas, oil, wood, and coal can be burned as fuel.

• Can you think of a time you’d need to burn gas, coal, or wood?

People burn wood on camping trips!

Coal grills help people cook food!

Cars burn gas to move!

Heat from Motion

Heat can also come from motion!

©FoodForTaught

Rub your hands together very quickly!

Your hands became warmer! That heat came from motion.

Stop and Do!

What did you notice?

Current Electricity

• Batteries make some toys and electronics work.

©FoodForTaught

• Batteries work because of current electricity.

• Current Electricity- a kind of energy that moves in a path.

• The path needs to be completely connected for the electricity to move.

Current electricity powers many of the things you use.

Current Electricity

• Current electricity can also come from wall outlets as well as batteries.

©FoodForTaught

• Current electricity can be changed into heat, light, or sound energy. It

can also make things move.

• Electricity runs through

wires into your house and into

the outlet.

Buildings called power plants change energy from coal, oil, wind, water, or the Sun into electricity.

Current Electricity

Think about if these items use batteries or need to be plugged into a

wall outlet.

©FoodForTaught

• What are some items that use current electricity in your house or

school?

This television uses current

electricity when it is plugged into a

wall outlet.

This toy puppy needs batteries to

make current electricity to help it

move.

Static Electricity

• They are stuck together because of static electricity.

©FoodForTaught

• Have you ever had a sock stuck on your clothes after they both came

out of the dryer?

• Static electricity is a kind of energy made by pieces of matter

that are too tiny to see. • Even though you can’t see them,

they are everywhere!

Static Electricity

• Sometimes you hear a static charge move from one object to another. We

often call this “getting shocked.”©FoodForTaught

• Like magnets, some of these tiny pieces of matter attract or repel

each other.• This causes them to have a static

charge.

• A static chargecan build up on one object and

jump to another.

The girl’s hair is attracted to the charged balloon, so

it sticks up.

Static Electricity

©FoodForTaught

• Lightening is an example of static electricity.

• Charges made in a storm jump between the clouds and the

ground. This is what lightening is.

1. Where does most of our heat come from?a) Burning Woodb) Rubbing our Hands Togetherc) The Sun

2. What kind of energy causes lightening?a) Heatb) Static Electricityc) Current Electricity

3. What kind of energy moves in a path and is used in batteries and wall outlets?a) Heatb) Static Electricityc) Current Electricity

Sound EnergySound is a kind of energy that we can

hear.

©FoodForTaught

• Sound is made when objects vibrate.

• An object can vibrate when it moves quickly back and forth.

• What are some sounds you hear every day?

Sound Energy• When something vibrates, air

around the object vibrates also.

©FoodForTaught

• Messages sent from your ear to your brain tell you what sound you

heard.

• The eardrum is the part of our body we use to hear sounds.

=

Different Sounds

• Think about the sound of someone whispering and the sound of

someone banging cymbals together. How are they different?

©FoodForTaught

Small vibrations make soft sounds, like the sound of a whisper.

Big vibrations make loud sounds, like the

sound of banging cymbals.

Different Sounds

• Sounds can be soft or loud, and they can also be low or high.

• Pitch is how high or low a sound is.• Fast vibrations make sounds with a

high pitch. • Slow vibrations make sounds with a

low pitch.

©FoodForTaught

This bell vibrates very fast when it is rung, which makes a high pitched sound.

This tuba vibrates very slowly when it is blown, which makes a low pitched sound.

What Sounds Move Through

• Sound can move through solids like wood or plastic.

©FoodForTaught

• If you put your ear against a wooden door, you can hear people talking in

the other room.• Sound is moving through the solid

door.

What Sounds Move Through

• Sound can also move through liquids.

©FoodForTaught

Have you ever been under water and heard sounds? What did you

hear?

• Many underwater animals communicate with each other by

making sounds.

What Sounds Move Through

• Most sounds we hear move through air.

©FoodForTaught

• Air is made of gases.

• The closer you are to a sound, the louder it will sound. The farther away you are from a sound, the

softer it will sound.

This man needs a megaphone so the

people further away can hear him.

1. What can sound travel through?a) Solids and Gasesb) Solids, Liquids, and Gasesc) Liquids Only

2. ___ is how high or low a sound is.a) Heatb) Vibrationc) Pitch

3. When an object moves quickly back and forth to produce sound this is called ____.a) Pitching b) Vibratingc) Sounding

Light EnergyLight is a kind of energy.

©FoodForTaught

• Why do you think you need light?

• What are some places that light comes from?

The SunFlashlights

Lightbulbs

• Most light on Earth comes from the Sun.

How We See Things• We see things when light reflects,

or bounces off of things around us.

©FoodForTaught

• The light that reflects off ofthese objects enters your eyes and

helps you see the objects.

• Smooth, shiny surfaces like mirrors can reflect

a lot of light.

How Light Travels• Light travels in a straight line.

©FoodForTaught

• Think about the light from a flashlight. When you turn it on a

straight beam of light shines.

• Light will travel in a straight line until it hits an object. Then it will

change directions.

When Light Hits Objects

©FoodForTaught

• Some objects are transparent.• Transparent objects allow light to

pass through them easily and do not make a shadow.

• Some objects are translucent.• Translucent objects allow light to

pass through them, but not as easily as transparent objects.

This glass door is transparent, so

light passes easily through it.

Waxed paper is translucent, so light can

pass through it but not as easily as it passes

through glass.

When Light Hits Objects

©FoodForTaught

• A shadow is a dark area where light does not reach.

• Shadows form when objects block light from shining through.

• Different objects let different amounts of light through.

• Opaque objects keep light from passing through them and allow

shadows to form.

This leaf is opaque, so the sun cannot pass through it and a

shadow is formed.
