The night after the John Glenn program, I pitched the terraforming idea to my students. I asked them if they'd like to terraform Mars as a big class project; I wanted to throw the idea to them and see how they would react. Already I had a vision of splitting the class into several groups and having each group take charge of a portion of the project. ... Following my initial idea on how to conduct the project, I split the class into six groups, each student choosing his or her group. ...
