Get Your Students Hired
I like the idea of having students pick which blood cell type they want to be and travel through a make shift heart in teh classroom. It gives me ideas for having students be Venous blood, traveling through the heart, other students act like the valves coordinating the movement. Also for the students to travel to another part of the clasroom acting as the lungs where they drop off a blue ball and pick up a red one. A good activity to wake everyone up and would make a great visual.
