Building Blood

As we continued our anatomy study, we moved from breathing to blood.  Froggy built this model of blood as
a method of telling back but also an opportunity for Froggy to teach her friend J.(roughly the same age) in a way both of them enjoyed.

Our model only had four ingredients like blood only has four main components.  The plasma is made from corn syrup.  We used about a cup.  The color is similar to plasma.  It took some convincing before J would believe that the majority of blood is really that color.

We used red hots for the red blood cells.  As you can see in the picture they share their color with the entire mixture as real red blood cells do. White jelly beans represented the white blood cells and gave the children a chance to see the relative proportions.  Sprinkles were added for the platelets.  Ours were bigger than they really should have been but close enough.  Froggy even demonstrated how they work by mashing them up against the side of the container over a "cut"
