Mrs. Winter’s 7th grade science class has been learning about body systems. To see firsthand the components of blood in action, we created simulated blood in a tub. The expandable red water beads represented red blood cells that carry oxygen throughout the body, the ping pong balls were the white blood cells, the red foam platelets clot the blood and the water served as the plasma for the cells to travel in. The students enjoyed getting elbow deep in a tub of blood!
