Blood Cereal!


Demonstrate the composition of blood by making blood cereal.

Plasma – milk with a drop of yellow food colouring. Add glucose and a little oil to demonstrate that nutrients are carried in the plasma.

Red blood cells – Cheerios stained with red food colouring.

White blood cells – small marshmallows for lymphocytes and larger marshmallows for phagocytes.

Platelets – Cornflakes crunched up to represent fragments of cells. The mixture can be passed through a fine sieve to demonstrate how the platelets clump and clot blood vessel lesions.

Mix into a big bloody mess!

(Although all of the ingredients are edible this is for demonstration purposes only and should not be eaten).
