This might come across as an odd post but I thought I'd give it a try and see what folks thought of the idea. I teach biology at a community college. Often times I am asked if I'd like to teach a continuing education class and those classes can be just about anything people find interesting. Judging by the way some folks both have interest in the TFP system I use and the way they glaze over a bit when I tell them about "the forum" (some folks want to be told rather than read, I think), I thought it would be fun to do a short con. ed. class on how to use the TFP system along with the app. Students could purchase a test kit as part of registration, bring their water in after we discuss water chemistry a bit. Could be fun. Good idea or nah? What pitfalls could I be looking at here? Thanks for all the help/advice past and future.
