Posted by Shannon

 Bottle:

The bottles represent the lungs.  We made the bottles so we  could learn  more  about  how lungs work.

lungrelax:

When the diaphragm is relaxed the lungs are deflated.
The balloon is empty.


lungpull:
When you breathe in your muscles pull on the
diaphragm and the lungs inflate.
The balloon is full.
