I developed this (and other) worksheets to tie calculus into the year of the Mathematics of Planet Earth, 2013. This worksheet asks students to apply their knowledge of linear functions, rate of change, and percentages to figuring out how much oxygen is available in Denver or on Mount Everest. The last question asks the student to critique their own linear model in discussion with peers and the teacher.
This single-page two-sided worksheet is for use in one class period as an application/supplement when students have learned about linear functions and rate of change. It is designed for group work, and could be used as a supplement for more advanced students.
The worksheet supports Common Core Mathematical Standard of Practice 4, Modeling, as well as Standard 3, Critiquing the Reasoning of Others.
