Lung Capacity

How much air can your lungs hold? This is what my seventh graders investigated on Thursday. They took a deep breath, and blew that one breath into a balloon, measured the diameter, and used a graph to convert CM to L. They loved it!

Here are some pictures of my crazy kids, who posed just for you guys!

Blowing up his balloon

He wanted to make a funny face. 

Finding the diameter of the balloon

Lung capacity fun!

I am in the process of uploading this to TPT if you want to do this lab.
