Procedure And Structure For An Instructional Laboratory Which Supplements Research, R. S. Adams Jr. Jan 1968

Procedure And Structure For An Instructional Laboratory Which Supplements Research, R. S. Adams Jr.

Journal of the Minnesota Academy of Science

This paper describes the organization of a laboratory course in Soil Chemical Analysis. Students select and pursue small research problems to gain experience in the soil analyses that are discussed in lecture and required in the laboratory. Involvement of the class in an actual research problem proved challenging to both the instructor and the class. The data obtained often supplemented current departmental research. Individual projects were found to be easier to supervise than team problems. This paper reports results of a team project examining parameters of a pot experiment. Shape of the pot, methods of watering, methods of fertilizing, and …
