Bones & Muscles

Science · The Human Body · conceptual

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

What mastery looks like

  • 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

Check your understanding

Can Bones & Muscles feel their own ribs or skull and explain what those bones are protecting inside?
