In this lung model science project, the straws represent your trachea and bronchial tubes, the balloons represent your lungs, the bottle represents your chest, and the plastic sheet is your diaphragm – a sheet of muscles under your chest. When you breathe in, or inhale, your diaphragm contracts and moves down, creating more space in your chest for your lungs to fill with air. When you exhale (breath out), your diaphragm relaxes back up. The space inside your chest gets smaller, forcing the air out of your lungs.
