Our class 5 scientist explored human biology by building working respiratory models. Collaborating in small groups, students used plastic bottles to represent the chest cavity, straws for the trachea, and rubber balloons to mimic the lungs and diaphragm.
This hands-on activity beautifully demonstrated the mechanics of inhalation and exhalation. It was a fantastic exercise that successfully combined teamwork, engineering, and oral communication with formative assessment.
