What is Energy?


Big Idea 10: Forms of Energy Grade 3 Benchmarks

• SC.3.P.10.1 Identify some basic forms of energy such as light, heat, sound, electrical, and mechanical.

• SC.3.P.10.2 Recognize that energy has the ability to cause motion or create change.


Energy is all around us!

–You can see energy as light from the sun or a lamp.

–You can feel it as heat warms things up.–You can see motion energy every time

you move.

What is Energy?

• Energy has the ability to cause motion.

• Energy has the ability to create a change.

Energy can change an object’s: motion shape temperature color


You use energy when you:– Take a walk– Lift a book – Throw a ball


What are the Forms of Energy??

Explore forms

•Light•Electrical•Sound•Heat/Thermal•Mechanical

/


What is Sound?

• Sound is a form of energy

• Sounds are made by a vibrations.

• Vibrations are back and forth movement.


How do we make sounds?

• We use our vocal cords to make sounds in our throat.

• When we speak, our vocal cords vibrate.

• Place your hand on your throat when you talk, and you can feel the vocal cords vibrate.


What can Sounds travel through?

• Sounds can travel through solids, liquids and gases.

• Sound travels through all matter.


What senses do we use to observe sound?

We can hear sound.

We can feel sound.

Sometimes we can see sound.


Loudness or Volume• Volume is the loudness or the softness of a sound.

• Loud sounds use a lot of energy.

• Soft sounds use a little energy.

• The more vibrations the waves have, the more energy, the louder the sound.

• Example: The harder a drum is hit, the more the drum will vibrate . The more an object vibrates, the louder the sound it makes.


TAG Reflections

• Tell a fact you learned about sound.• Ask a question about something you don’t

understand about sound.• Give another idea that you’ve learned in our

study of energy.


It’s Electricity, a Kind of EnergySong

It makes a light bulb shine. It makes a radio play. It makes an oven bake. What is it?Chorus

It makes a washer wash. It makes a dryer dry. It makes a streetlight glow. What is it? Chorus

It makes a wall clock tick.It makes a telephone ring.It makes a blender mix.What is it?Chorus

It makes a vacuum sweep.It makes a TV play.It makes a doorbell ring.What is it?Chorus:It’s electricity—a kind of energy that gives us light and heat and power.


What is electrical energy?

• A form of energy that is produced when electrons move from one place to another.

• Electrons are particles that are in the space around the nucleus of an atom.

• The forces of attraction and repulsion make electrons move.

What is Mechanical Energy?

• Mechanical energy is energy due to motion.

• Mechanical energy can be stored energy of position that could cause change in the future.



What is light?

• Light is something that allows us to see objects.• Light is a form of energy. • Light is produced by the vibrations of electrically

charged particles.• Light travels in waves.


What is Heat Energy?• Heat is movement of energy from one place to

another.

• Temperature is a measure of heat energy.

• A thermometer is the tool used to measure temperature.

• Every time energy changes form, it gives

off some unusable heat.Reading a Thermometer


What happens in Heat/Thermal Energy ?• Energy is the movement of the atoms in an object.

• Heat is the movement of energy from one place to another.

• When any form of matter gets warmer, the kinetic energy of its atoms increases.

• The object’s particles move faster, so its heat/thermal energy increases.

• A change in thermal energy can lead to a change in phase or state of matter:

- Ice melts from a solid to a liquid.

- Liquid water changes to water vapor.



What do you know about Electricity?

• Electricity gives power to machines.

• Look around the classroom• Find at least three things that use electricity or

electrical energy. • List them in your science notebook.• Electricity is a kind of energy we use every day.


Concept Review: Forms of Energy

1. What is energy? Answer: Energy is the ability to cause motion, or make changes in an object.2. What are the forms of energy? Answer: They are light, mechanical, sound, heat, and electricity.3. What forms of energy can be observed using our senses? Answer: We can see energy when it is in the forms of motion and light. We can hear sound and we can feel heat.
