Description
Summary:Prstojevich et al developed an activity that provides a review of, or introduction to, the gas laws as they pertain to respiratory function. Another problem that often arises in teaching this section is the diversity of student interests. Some students are motivated by crime scene approaches. Others have a strong interest in conservation biology and ecology and are more interested in animals and comparative physiology. This activity can be tailored to either audience using either a crime scene based on the Fixing the Pool comedy routine by Jon Reep, or discovering how elephants manage to snorkel at greater depths than humans. In this activity, they have scenarios involving snorkels to motivate a hands-on activity that allows students to work out, without doing any math, an understanding of the overall principles of the effect of volume on pressure and their implications for snorkeling.
