Each student or pair of students is provided with an illustration of a landscape, landform, or geomorphic process and asked to place it in the appropriate location on the timescale answer form (Acrobat (PDF) 8kB Feb28 12) (see the list of landforms and geomorphic processes (Excel 74kB May8 12)). The landforms and processes list includes information on time ranges for each time, time in seconds, and time in years. Note that the time ranges represent approximate values for the processes and that the time in seconds and time in years columns represent low-end values for each respective process. Thus, some processes may fit into multiple locations on the timescale answer form and some revision by students will occur during the initial phase of the activity. After students have completed their first iteration of the timescale, the instructor will assess the placement of each process on the answer form (Acrobat (PDF) 8kB Feb28 12). The instructor will then determine which processes need further explanation. For some processes, lecture or other learning strategies might be implemented if students do not have a good understanding of the scale in which they occur. For other processes, the instructor may facilitate a discussion to lead students to expand, contract, or alter their perceptions of the time range. Ultimately, and perhaps towards the end of the lecture period or as a quiz, students will again be asked to complete the timescale answer form.
