What is blood made of?
There are four main components of human blood: plasma, red blood cells, white blood cells and platelets. To show how these ingredients come together to make blood, we used water and yellow food colouring to represent plasma. We used hooped cereal and red food colouring as red blood cells. You might be able to spot the white marshmallows that represent white blood cells, along with the mini pompoms which were used as platelets. This lesson really helped us to visualise and remember the different components.
