Pudong Grade 4: The Magical Respiratory System

‘Puff pant. Puff panthers.’

The fourth graders built a model of the respiratory system on March 9th. It was model of a thick milk tea straw sticking out of an empty bottle of water with two thinner straws at the end of the milk tea straw. A balloon was tied to each of the two thinner straws, to represent the lungs. The bottom was cut out by the teachers before hand, so the students could wrap a rubber glove around the bottom. The cool thing is, if you pull and let go of the rubber glove, the balloons actually contract and expand, just like our diaphragm and lungs!
