I want to emphasize that Connor did this completely on his own, without any help for either his mother or I. We were watching an episode of Bill Nye, the Science Guy about the Heart, and Connor noticed that his mother's yoga ball pump was just like a heart (complete with red and blue ends) and that the shower caddy ...that was going to be donated looked like a rib cage, esophagus and stomach, and it just snowballed from there. The end result is as follows in the pictures. I just have to say that unschooling rules!
The first picture is of the overall body with the various parts labelled, and the second is a close-up of the "inner workings" labelled with Connor's rationale for why each part was chosen. (Click on each picture for a bigger image)
