This lecture/activity is for a college introductory Environmental Geology course with enrollments up to 75 students. The class is held in a large lecture classroom and was completed during a 75 minute class period. These lesson is situated towards the middle of my course, but does not require prior knowledge to complete. Students do complete "homework" assignments prior to class which act as pre-work on the topics. I use
Description and Teaching Materials
The pre-assignment is a water cycle digital game created by Dr. Emily Fairfax. The game files can be accessed by contacting her through her website: https://emilyfairfaxscience.com
The activity is built into the lecture. Notes about the lecture are included in the slides and all images have alternative text describing the image. During the lecture I ask students questions as an entire class periodically. The students also answer the worksheet questions as indicated in the slides. The first direct water calculation (Question 5) is completed individually. Then when the students try to cut their daily water use (Question 6) they work in pairs or groups of three.
