To learn more about how the respiratory system works, BYQ’s fourth graders simulated a lung. Inside a bottle, the lung was a balloon, the trachea was a straw, and the diaphragm muscle was a cut balloon. When Mrs. Schochet’s students pulled down on the “muscle,” the “lung” expanded and filled with air! When the muscle was released or pressed up, the air went out of the balloon, and the “lung” deflated.
The girls gained appreciation for HaKadosh Baruch Hu’s marvelous creation of our respiratory system. The lesson continued with a STEM project, where the girls made balloon-powered cars!
