Lungs Model

thingiverse

Lungs Model built using a plastic bottle, three baloons (two of them red) and two flexible pipes. The baloon at the bottom works like the diaphragm, the muscle that expands and contracts causing lungs to fill with air and then empty out again. The movement of the red balloons matches the breathing, when a person breathe in, the lungs fill with air, that’s because the diaphragm expanded making room for air to get in through the bronchus (in our model the joint pipes). When a person breathe out, the diaphragm contracts pushing all the air out of your lungs. The students can enjoy creating a new face for the model.

Lesson Plan and Activity Built the model Cut the bottle in the middle. Create two small holes on the bottle cap. Insert the two red baloons on the cap holes. Insert two small pieces of flexible pipe on the hole, this allows the air flow inside the ballons. Join the two pipe end with the piece built with 3d printer. Cut the top of the third baloon and apply it on the bottle bottom. Fix it with the ring built with 3d printer. Create with the students a funny face for the model, print it and apply it on the top of the bottle. Materials Needed Materials: plastic bottle, three baloons (two of them red) and two flexible pipes. 3d print of the .stl file attached.
