In science Helvellyn have begun to learn about the circulatory system. The first thing we looked at, was 'what is blood? What is it made from? What does blood do?'

To understand the components of blood, we made our own edible blood using similar looking ingredients and trying to get the correct percentages of each component. 

We used:

apple juice - plasma (55%)

cherries - red blood cells (44%)

hundreds and thousands - platelets (0.5%)

marshmallows - white blood cells (0.5%) 

We looked at what each part of the blood does and how it helps our bodies.
