Making blood

In Science in 6KL we have been learning about the Circulatory System. The children have been very enthusiastic in our Science lessons and have shown great curiosity, and that did not change this week.

In order to help the children understand what blood is and what is in blood, we created a class ‘blood model’ in last Friday’s lesson.

The children were incredibly excited and at the end of the demonstration could explain in detail what was in our blood and why each element is so important.

In case the children would like to share the model with you at home, the ‘ingredients’ can be found below:

- We used water, yellow food colouring and a sprinkle of salt to represent plasma and the nutrients, vitamins and minerals found in it.

- We added ringed cereal (such as Honey Loops or Cheerios) along with red food colouring for the red blood cells, which carry oxygen from the lungs to the heart and then the rest of the body- the class were amazed when the red food colouring mixed in!

- Small white marshmallows to represent white blood cells, which create antibodies to identify and fight off infections/illnesses.

- Small sweets or colourful chocolates to represent our platelets, which help our blood to clot if we are hurt.
