Described is an independent study project for students in chemistry at New College, Sarasota, Florida. Six students collected and analyzed local plants to determine content of alkaloids, terpenes, and flavonoids. (RH)

Describes a series of experiments designed for general chemistry in which the students prepare metal complexes which are then used as samples for spectral study. (SLH)

Describes a technique of quantitative analysis based on measuring the temperature change accompanying a quantitative reaction in solution. Can be used for delta-H measurements and quantitative determinations by comparison of data obtained for an unknown with that obtained for a series of standards. (SLH)

Describes a procedure for freeing an element from either a mineral or organic matrix with the use of a radioactive tracer to determine recovery of the elements. (SLH)

The study reported here had two main aims: to collect data relating to verbal participation in 'conventional' tutor-led groups and to examine the feasibility of using leaderless groups in university teaching. (Author)
