A ready-to-teach Year 6 science lesson exploring the structure and function of arteries, veins and capillaries.

Pupils compare vessel walls, lumen size, valves, blood pressure and direction of blood flow before working collaboratively to build large 3D blood vessel models. Includes clear explanations, questioning, a gallery-walk investigation, gap-fill consolidation and a greater-depth mystery vessel challenge linked to restricted arteries, heart attacks and strokes.
