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

1 approach
Heart & Blood Circulation means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A simple body outline printout or drawing; Pencil and labels. 1. Say the goal of Heart & Blood Circulation in plain words once. 2. Adult points to one organ or system and names its job in plain words. 3. Child labels three parts and says the job of each. 4. Fresh check: one fresh organ/system job. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

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?”
