My Steam project is a review of the components of the blood.  I used clay to represent red blood cells, different types of white blood cells, and platelets.  My report discusses each type of cell in more depth and what role each plays in the body.  Each type of white blood cell is responsible for attacking different antigens. Balance in the blood between red and white cells is critical to good health.  Too many or too few of either can be life threatening.  Therefore, I also briefly discuss two types of blood diseases, leukemia, and anemia.  Blood and what is in it is so critical that 5 million Americans require blood transfusions every year.
