6. A little bit of blood and gore (blood models)
Today we will be making blood our own blood just on a larger scale. Our blood is made up of four main components: white blood cells, red blood cells, platelets, and plasma - each of which serve specific purposes. At your tables make sure to pick up one of each of the following from the front. Come to the front to use other materials as needed.
