Heart & Blood Circulation
Describe the circulatory system in detail: the heart has four chambers (two atria, two ventricles) that pump blood in a double loop — one to the lungs for oxygen and one to the rest of the body to deliver it — through arteries, veins, and tiny capillaries
Lesson
Set out your lesson
“Heart & Blood Circulation means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A simple body outline printout or drawing
- Pencil and labels
Extra for the adult
Worked example. The brain sends signals so muscles know when to move.
Optional challenge. For Heart & Blood Circulation, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Heart & Blood Circulation, not mastery.

Check understanding
- Name the four heart chambers and describe the double-loop pathway (heart → lungs → heart → body)
- Distinguish arteries (carry blood away from heart), veins (carry blood back to heart), and capillaries (tiny vessels where exchange happens)
- Name the components of blood: red blood cells (carry oxygen), white blood cells (fight infection), platelets (help clotting), plasma (liquid)
“Can your child trace the path blood takes through the heart and body — explaining that it goes to the lungs first for oxygen, then out to the rest of the body?”
