Science Model

Any guesses?

Kathleen and Mikey are reading Blood and Guts. I love this book for their level.

They got to the section on lungs and decided to make a lung model...

...complete with a working diaphragm (cut off balloon on the bottom) to show that when it's relaxed (or arched up), the lungs deflate, exhale.

Now that the lesson is over, Jimmer has given this lung a workout!

I wish I had been able to make lungs in my physiology lab.

We're looking forward to finishing up the book with some more fun tests and experiments for the eyes, ears, balance, and nervous system.
