Description of the activity/assignment

This is a basic introductory online exercises that introduces students to landslides. Students complete a background reading about landslides in general and answer a series of questions. Students then complete a background reading about the numerous debris flows that occurred near Boulder, Colorado in 2013. Students determine answers to questions from the text as well as interpreting graphs and maps.

Determining whether students have met the goals

Students complete the exercise during the week it is assigned. Upon completion of the laboratory exercise, students must complete an online quiz that consists of the same questions in the exercise. The online quiz is within the Desire 2 Learn (D2L) online learning platform, so answers are automatically graded and imported into the student's grade book.
