What’s in a Drop of Blood?

We are starting our human anatomy unit in 2018 with a look at blood!

Blood is the life force of all people and animals. Leviticus 17:11 says, “For the life of the flesh is in the blood.” Blood plays an important role in keeping our bodies functioning as they should. It not only keeps us alive, but delivers oxygen and nutrients to our organs, muscles, brain, and limbs. It attacks foreign invaders when we get sick and heals us by building a protective wall around cuts and scrapes.

In our experiment, we assembled the major components of blood: red blood cells, white blood cells, platelets and plasma. While it does lots of other things, we focused on these four items in this experiment.

To do the experiment, we used:

Corn Syrup (Plasma)
Red Hots (Red Blood Cells)
White Beans (White Blood Cells)
Oats (Platelets)

First we added the plasma, which makes up about half of blood. The plasma is the fluid mixture that lubricates the cells.

Then we added the red blood cells. It was pretty thick to mix, but the viscosity helps hold the cells in place.

The we added the white blood cells.

And finally mixed in the platelets.

As we were making it, we went over what each cell does and how it functions in the body.

The kids thought it was so neat to make blood. It looks like they have seen in books and being able to see what actually goes into it helped bring that concept to life.

  1. Thank you for the post! We just started our circulatory system studies and my kiddo is a very hands on learner. The corn syrup kept everything suspended quite nicely. I think he really enjoyed this model and he is looking forward to “teaching” his father what he learned later today.
