🦴 Bones hold you up
A child may say bones "are the heart" or that bones move on their own, because both bones and the heart are hidden inside the body and treated as one mysterious "insides" category, rather than as separate parts with separate jobs.

- Bones hold the body up.
- Muscles pull and move.
- Without bones we would be like a soft sack.
- The heart is a living pump. It is not a bone.
The mistake most kids make here
Bones are the heart, or they move by themselves with no muscle.

Bones mainly…
Bones
- are the heart

Answer
hold the body up — Yes. They are the body's beams.
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: Say what bones do and what muscles do.
How to help at home
Because you can't see bones, muscles, or the heart directly, a young child often lumps everything under the skin into one vague idea of "insides." Giving each part one clear job — bones hold up, muscles pull and move, the heart pumps blood — is more useful than a diagram at this age.
Tonight, have your child make a fist and then let her hand go floppy. Ask what changed. Point out that her arm bones didn't change shape or move by themselves — her muscles pulled to make the fist, and let go to make it floppy. Bones are the frame; muscles do the moving.
When she calls a bone "the heart" or says a bone "moved itself," ask: "is this part pumping blood, or holding your body's shape?" That question sorts hidden body parts by job rather than by simply being unseen and unfamiliar.
A good sign she has it: she can explain that without bones, her body would flop like a soft sack — and that it's her muscles, not the bones themselves, doing the pulling when she moves.
Questions parents ask
- Why does my child think bones and the heart are the same thing?
- Both are hidden inside the body, so a young child often groups anything unseen under one vague "insides" idea. Giving each part a distinct, concrete job — bones hold, the heart pumps — helps separate them.
- Do bones move by themselves?
- No — bones provide the body's frame and shape, but muscles are what pull on bones to create movement. Bones can't move on their own; they move because a muscle is pulling them.
- What's a simple way to explain bones and muscles to a 7-year-old?
- Bones are like the frame of a tent — they hold everything up in shape. Muscles are like ropes that pull on the frame to make it move. Without the frame (bones), the body would flop; without the ropes (muscles), the frame wouldn't move.
- How does Maya teach this differently from a body diagram?
- Maya asks what a specific body part actually does — hold up, pump, or pull — so the child sorts by job rather than memorizing labels on a picture.
