More Kitchen Science: What’s Inside a Drop of Blood?

What we made:

A model of a microscopic drop of blood.

How we did it:

We mixed karo syrup (plasma), red cinnamon candies (red blood cells), dry lima beans (white blood cells), and lentils (platelets).

How we kept the toddler busy during the experiment:

Sensory bin of lentils and dry lima beans (left over from the experiment) plus some rice, spoons and containers for filling and dumping.

Pouring all the ingredients into the container.


What a drop of blood would look like under a microscope.

This is from our R.E.A.L. Science Odyssey Life curriculum unit on The Human Body.  The curriculum includes two worksheets that consist of diagraming and labeling a drop of blood but since Firefly seems to be highly allergic to worksheets and The Queen Bee is a bit young for these particular science worksheets, I decided to turn it into an art project instead.

I drew large drops of blood onto big pieces of white butcher paper, then read clues to the kids. They figured out which were the white & red blood cells, the plasma and the platelets and colored them the coordinating colors.

Love Bug kept right on playing with the sensory tub while the older two colored their "blood pictures". It was a big hit and we put it away for another day when I need him to be occupied.

Almost finished. We then labeled each part and wrote what jobs each is responsible for (clotting, fighting germs, delivering food, etc.).

    I LOVE, LOVE, LOVE this experiment! I am a complete visual learner so this really did it for me. We just read that book Drop of Blood and the kids loved it. I am so going to have to try this with them!
