What you’ll learn

  1. Energy Is EverywhereUnderstand that energy is the power to make things happen and that it is all around us.Energy is what makes things happen — moving, heating, shining, and making sound. It is invisible, but we see what it does everywhere. Even our own bodies run on energy from the food we eat.
  2. Meet the Kinds of EnergyName the main kinds of energy — kinetic, heat, light, sound, electrical, and chemical — and give an example of each.There are many kinds of energy. Kinetic energy is movement, heat energy warms things, light lets us see, sound is what we hear, electrical energy flows through wires, and chemical energy is stored in batteries and food. Each kind helps our world work.
  3. Stored and Moving EnergyTell the difference between stored and moving energy and understand that energy changes form without being lost.Stored energy is saved up, ready to be used, like in a stretched rubber band or a battery. Moving energy is energy in action. Energy can change from one kind into another — for example, a battery's stored energy becomes light in a torch — but it is never truly lost.

Questions this course answers

What does energy let things do?

Energy is the power to make things happen, such as moving, heating up, shining, or making sound.

A ball rolling fast across the floor has which kind of energy?

Anything that moves has kinetic energy, and a rolling ball is moving, so it has moving energy.

Which kind of energy do we hear with our ears?

Sound energy is what we hear. Things like drums shake the air, and that shaking reaches our ears as sound.

Where is chemical energy stored, ready to be used later?

Chemical energy is stored energy held inside things like batteries, fuel, and the food we eat.

A stretched rubber band is an example of what?

A stretched rubber band holds stored energy that is set free as movement when you let it go.

When you turn on a torch, the battery's stored energy mostly turns into what?

The battery's chemical energy becomes electrical energy, and the bulb changes that into light and a little heat.
