Using a cup, straws, balloons and tape, Middle School students created lungs. The cup represents the chest cavity and tape which seals around the straw is the nose and mouth. Inside the cup, the straws replicate the bronchi and trachea. Lungs are placed at the bottom in the form of balloons. The bottom of the cup is covered with a large balloon to stand in place of the diaphragm. When pulled, the lungs inflate!
