As part of their general education studies, all students at the University of Kentucky must take two natural science courses. Many non-science majors choose the biology sequence of courses. Unfortunately these courses are lecture-only courses, and so some students can graduate without ever having had a science laboratory course. In an effort to provide students with some laboratory experience, I have developed / adapted a number of laboratory activities, which I have successfully incorporated into a non-majors biology course (Human Ecology). These activities are carried out in a lecture hall with 300 students in 50-minute time periods. In this chapter, two of these laboratory activities are presented. 1) Soil Testing - students test soil samples for nitrogen, potassium, phosphate and pH; compare the relative fertility of different soil samples; and carry out an inventory of animal and microbial life in soil samples. 2) Water Pollution Testing - students examine the effects of household chemicals on water quality (from Using Fast Plants and Bottle Biology in the Classroom, published by National Association of Biology Teachers, 1994, ISBN #0-941212-17-3).
