Blood Sensory Bin


It’s been a while since we went through a teaching unit on here!  I’ve had these activities in the works for a few months now, and they have been so much fun for the kids and myself.  So today I’m going to share a fun sensory idea that you can implement into your weekly activities for toddlers and preschool children.


Since I don’t think anyone is interested in letting their children play with real blood, I came up with a creative way to teach young children the different things that reside in their bloodstream.


These cute larger pom-poms (Purchased at Michael’s) serve as the germs.  You could also call them bacteria, infections, or a virus, but germs is much less complicated for this age.  All I did with these is glue some googly eyes to make them cute (because the cuteness factor is important to children y’all!).

Red Blood Cells


The red blood cells are just straight up red pom-poms, purchased at Michael’s crafts.

Red blood cells carry oxygen all over your body, and they also remove carbon dioxide.

White Blood Cells

For the white blood cells, I used white pom-poms (Michael’s).  I glued some small googly eyes on them as well.

White blood cells help your body fight off infections.



Platelets were cut out with a small “sun” shaped lever punch.  They reflect what I researched on platelets and are an important part of the circulatory system.

Platelets help your blood clot.

Flash Cards


On some flash cards I labeled the different organisms you’d find in the blood, and on the back is the picture to help the child match the word with the image.

  • Red Blood Cells (red pom poms)
  • Platelets (small blue “sun” cut-outs)
  • White Blood Cells (white pom poms with googly eyes)
  • Germs (large multicolored pom-poms with googly eyes)
  • Flashcards (with the names of each organism mentioned above and a picture of them on the back)
  • Tongs (our favorite for tiny hands are the ones from the dollar tree, in the plastic cutlery section)
  • A bin or tray to hold your “bloodstream” in



I even found these little plastic trays inside my mini cupcake liners, and thought they looked like tiny petri dishes!  So we used them to place each item with its proper label.

I hope you’ve enjoyed this activity, and thanks for stopping by!
