I remember a while ago in high school, the teacher broke us up into groups and gave us an exercise to do. It entailed each group is given a list of "survival materials" that they could take with them to cross a desert. Then each group had to list the materials in order of which would be most useful to least useful.

If anyone remembers this activity/could tell me where to find it I'd appreciate it, since I need it for a class presentation.

Thanks!
