Inexpensive metal probe meters that are sold by garden stores can be evaluated by students for their accuracy in measuring soil pH, moisture, fertility, and salinity. The author concludes that the meters are inaccurate and cannot be calibrated in standard units. However, the student evaluations are useful in learning the methods of soil analysis…

Describes a topographic map exercise designed for lab session of two to three hours in an introductory geology course. Students are taught the basic principles of topographic map construction and are then required to make a map of a section of campus. Author claims the approach has improved student test performance and resulted in a deeper…
