As we continued our anatomy study, we moved from breathing to blood. Froggy built this model of blood as
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"
