Description of the activity/assignment

Students use the soil survey to familiarize themselves with physical geography of the county and the basic soil properties of the soils their campus is built on. Students navigate all the major parts of the table including the introductory narrative, soil series descriptions, tables, and maps. This exercise is used to prepare students for a subsequent exercise describing the soils on campus by collecting a bucket auger profile.

Determining whether students have met the goals

Students complete the exercise during a 2-hour laboratory session. Students are expected to work independently or in pairs. Upon completion of the laboratory exercise, students must complete an online quiz that consists of the same questions in the exercise before the next lab meeting. 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.
