We all know that we breathe using our lungs. And most of us think we understand the physics of why air leaves our lungs as we exhale - we can feel our rib cage contracting and we know that when you squeeze a balloon or a ball, air will come out if there is a hole. But most of us don't know actually why air goes into our lungs - we just know it does. In this activity you will make a model of your lungs that shows how they work. Materials:
Parent Tip: This model shows how the movement of the diaphragm causes lungs to expand and contract. The movement of the rib cage also helps with this but is not included in the model because it is secondary to the diaphragm. How To Links & Explanation: Here is the link to the instructions and explanation. Thanks to Science Sparks for this activity.
