Geologic Time Discussion Analogies part of Cutting Edge:Rates and Time:Teaching Activities
This is 4 ppt slides used to facilitate discussion w/students about the immensity of geologic time. I ask them a series of leading questions and try to get them to do "mental math" in order to grasp the immensity of billions of years.
Teaching about Time part of Workshop 2012:Essays
Below is an itemization of the challenges I encounter and methods I use (or don't use, as the case may be) in teaching temporal concepts. They are all in the context of geologic time and the techniques used therein. For some context, these are all related to a 15-week Physical Geology class at Pima CC where I have usually 2 class periods w/labs (total ~5 hrs) to cover the topics.
