This interrupted case study tells the story of Miles, a freshman in college, who volunteers to help with the composting program on campus. Miles is excited about composting but his mother is hesitant to try it at home. Miles learns about the key ingredients for successful composting and his mother eventually begins to see its value. This case is presented in four parts, and can be used with or without the PowerPoint presentation and associated clicker questions (see Supplemental Materials). First, students are asked to analyze waste that they generate at home and identify any material that is compostable. Next, students explore the science of composting. Finally, students explore the topic of human manure to consider composting to the extreme. The case was designed for an environmental science course for non-majors; no prerequisite knowledge is assumed.
