I drew an enormous chalk figure of the human body in our unfinished basement, and made sure to include the trachea, lungs, heart, arteries, and veins. I also pulled out my red and blue unifix cubes for the blood. I also grabbed some cans of silly string we had sitting around.
Example #1: We tossed all the red cubes in a ginormous dump truck from my daughter's sandbox. I told Boo that the blood goes to the lungs to get air, then we blew on the red blocks. We delivered red oxygenated blood by "driving" the truck down the arteries and tossing red blocks throughout the body.

Example #2: We cleaned up the blocks and played the game again, but this time we used silly string. And it was a lot more captivating. We started at the heart, went to the lungs to get our air, then back down the heart and into the arteries. My daughter enjoyed squirting the silly string throughout the body, although she had a difficult time pushing down on the valve. The silly string...I mean oxygen.... was picked up in the trusty dump truck along the vein path and hauled away to the lungs, were it was exhaled.
|After picking up the carbon dioxide (silly string), Boo dumped it into the lungs. Right after doing this, she picked up the silly string and exhaled it by running up the trachea and out the mouth.|
|Look at our body develop- this is turning out to be such a fun project!!|
I couldn't resist adding this cute School House Rock video on the circulatory system. It's classic, educational film at it's best.
