⚡ Energy changes form
The word 'energy' often means only electricity to a child, when heat, motion, light, and electricity are all the same underlying thing appearing in different forms, and each can turn into another.

- Energy is what lets things happen: to move, to warm, to shine.
- It shows up in several forms, and motion is one of them.
- Heat is another form, and electricity a third.
- They can turn into one another, which is why we can say they are the same thing.
The mistake most kids make here
Thinking energy is only electricity, and heat is something else entirely.
Try one question
Heat, motion and electricity. What are they?
They are
- three names for water
- forms of energy
- kinds of rock
Answer
forms of energy — Yes. The same energy, three forms.
How Maya teaches it
Your child tells Maya what they did in class. She teaches this topic at her desk, asks questions with tappable answers, and when the answer is wrong she explains why that answer was tempting instead of saying “try again”. She remembers what did not land and comes back to it.
Your child has it when they can: What lets us say heat and motion are the same thing?
How to help at home
Electricity is the most visible, named use of the word 'energy' a child hears — on a battery, a bill, a plug — so it's natural to think that's the whole category. Heat and motion don't come with the same obvious label.
Tonight, try rubbing your hands together quickly and feeling them warm up. Ask your child where that heat came from — there's no battery or outlet involved, just motion turning into warmth, which is energy changing form right in their hands.
If your child says heat and electricity are unrelated, ask 'what happens to a lightbulb or a phone charger after it's been on a while?' Both get warm — because some of the electrical energy is turning into heat, which is the same kind of thing under a different name.
A good sign they've got it: they can give an example of energy changing from one form to another, like motion becoming heat, without you naming the forms for them.
Questions parents ask
- Why does my child think energy is only electricity?
- Electricity is the most commonly labeled form of energy a child encounters — on batteries, bills, and appliances — so it can seem like the whole idea. Feeling hands warm up from rubbing shows energy in a form with no electricity involved at all.
- How are heat and motion the same kind of thing as electricity?
- They're all forms energy can take, and each one can turn into another — motion can become heat through friction, electricity can become heat in a wire, and so on — which is why scientists group them under one word.
- Can energy just disappear?
- No — energy changes from one form into another, but the total amount doesn't vanish; a spinning top slowing down is turning its motion into heat and sound, not losing energy altogether.
- How does Maya teach this differently from a textbook definition?
- Maya asks what heat, motion, and electricity actually are, using real options like 'three names for water' versus 'forms of energy,' so the child has to reason toward the connection instead of just memorizing it.
