IB Biology: Modeling Respiration

Seniors in IB Biology HL Year 2 with Mrs. Gallina spent time today modeling respiration.  Rather than using stand and deliver, Mrs. Gallina used household items and asked the students to create a model of human lungs, the thoracic cavity, and the diaphragm then describe how the system works using key terms such as pressure and volume.  Below you’ll see a short video of Shannon and Aine explaining the process (with an appearance in the background by Chris) as well as a slow motion video of their simple model in action.  Well done!
