About

Are you curious about how our lungs work? Lungs help us breathe. When we take in air – either through our mouth or our nose – it travels down a tube called a trachea and into our lungs. With the help of a muscle called the diaphragm, our lungs expand and contract to move air in and out. This experiment will teach participants to build a model of our respiratory system to better understand the process of respiration.
