We've been continuing our study of the human body this week and today we focused on the lungs and how they work. We made this model of a lung and diaphragm after reading about lungs in a couple of our body books.
The model was easy to assemble with minimal time and supplies needed. My boys were especially happy to drink some Root Beer so we could get the bottle for this project!
It was actually really cool to see how moving the "diaphragm" up and down would make the balloon lung fill and deflate. You could also put the mouth of the bottle up close to your face and feel the air coming out. The 9 year old said "I really like this!"
I'm sure we'll be revisiting this project in the future with the younger ones!
