Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.
