Thames Class - What is blood?

Today in Science we learnt about the components of blood, their functions and the different blood groups. We started the lesson by writing a sentence that defines blood, we revisited this at the end of the lesson and refined our definitions. To help us understand each component we made blood using Cheerios, red & yellow food colouring, marshmallows and porridge oats. First we dyed the Cheerios red and these represented the red blood cells. Next we added the marshmallows, which represented the white blood cells, and the oats which represented platelets. Before finally mixing yellow food colouring with water, which represented plasma, and adding this to the mixture. 

We then went on to refine out definitions of blood before  looking at microscopic images of red blood cells, white blood cells and platelets. We then used these images to work in groups to create paints and drawing of each component.
