What is blood made up of?  In this lesson we learned what makes up our blood.  We found that our blood is 55% plasma, <1% white blood cells and platelets and 44% red blood cells.  We made an artificial ‘blood sample’ using vegetable oil, syrup, food colouring and milk to represent the different components.  This created our own centrifuge, just like a scientist would use!
