Bones & Muscles

Know that the body has a skeleton made of bones inside it that gives the body its shape and protects important organs like the brain (skull) and heart (ribcage), and that muscles attached to bones allow the body to move

Lesson

Set out your lesson

“Bones & Muscles means knowing bones shape and protect the body, and muscles pull on bones so we can move. We will practise once together, then check a fresh example.”

Bring to the table

  • Simple body sketch or printable skeleton outline
  • Labels: skull, ribcage, spine, muscles
Extra for the adult

Worked example. The skull protects the brain. The ribcage protects the heart. Muscles pull on bones to make movement.

Optional challenge. For Bones & Muscles, add leg bones and say which muscle helps kick a ball.

What to notice. Keep one parent note: bones labelled; muscle pull; support used. This session samples skeleton basics, not mastery of anatomy.

Selected Default Gakuva

Bones & Muscles means knowing bones shape and protect the body, and muscles pull on bones so we can move. We will practise once together, then check a fresh example.

Spend about 12 minutes naming three bone groups, feeling a gentle muscle squeeze, then checking a fresh label.

Check understanding

  • State that bones give the body shape, support, and protection
  • Name at least three bones or bone groups (e.g. skull, ribcage, spine, leg bones)
  • Explain that muscles pull on bones to make the body move
“Can your child feel their own ribs or skull and explain what those bones are protecting inside?”
