All That Blood

This week in science, Year 6 explored the components of blood and the important jobs each part performs inside our bodies.

To bring our learning to life, we created a model of blood using everyday items: Cheerios represented red blood cells, marshmallows became white blood cells, rice stood in for platelets, and orange squash with a pinch of sugar acted as the plasma.

As we built our mixtures, we learned that:

• Red blood cells carry oxygen from the lungs to the rest of the body and transport carbon dioxide back to the lungs to be breathed out.

• White blood cells help defend the body against germs by fighting infections and destroying harmful bacteria and viruses.

• Platelets allow blood to clot, helping to seal cuts and prevent too much bleeding.

• Plasma is the liquid that carries nutrients, hormones, waste products and all the blood cells around the body.

After creating our models, we used our new understanding to write information texts explaining how these components work together to keep us healthy. It was a fun, hands‑on lesson that helped us visualise what’s happening inside our bodies every day!
