The Heart & Blood

Science · The Human Body · conceptual

Understand that the heart is a muscle that pumps blood around the body through tubes called blood vessels, and that we can feel our heartbeat by placing a hand on our chest or fingers on our wrist

What mastery looks like

  • Locate their own heartbeat by touch (chest or pulse point)
  • State that the heart pumps blood through the body continuously
  • Describe blood vessels as tubes that carry blood to every part of the body

Check your understanding

Can The Heart & Blood find their own pulse on their wrist or neck, and explain that it’s their heart pumping blood?
