Describes an introductory course for college students which consists of a series of questions related to a report on bacterial contamination of glucose drip bottles. The students discuss and conduct their own experiments. Summarizes student and staff response to this course. (Author/EB)

The 35mm transparency projector and the overhead projector are described as being useful as teaching aids. Experiments are suggested. (Author/EB)

A method is described for the construction of 3-dimensional map models which are portable and strong enough to be taken into the field. The construction method involves alternating portions of colored maps between sheets of perspex of a thickness which will give the vertical exaggeration desired. (BR)

Describes a model system to illustrate many of the biochemical and chromosomal processes involved in the transmission of genetic material. Uses commercially available beads. (BR)

Describes an arrangement of a laboratory course in biochemistry designed to teach currently used biochemical techniques and then have students apply the procedures in a real research program so as to give students a better understanding of biochemistry. (BR)

Describes how to use playing cards as simulators to demonstrate several aspects of allelism and allele frequency in a gene pool. They provide an "unexpected" result, promote group discussion and may stimulate students to devise variations for comparison. (BR)

Describes two exercises which use data of sporting events (running) in conjunction with biological factors as exercises in interpreting data. (BR)

Describes construction and use of a simple auxanometer which students can use to accurately measure root growth rates of intact seedlings. Typical time course data are presented for the effect of ethylene and indole acetic acid on pea root growth. (Author/BR)

Describes a hydrobiological field course for undergraduates that investigates river pollution but can also be adapted for still waters. (MLH)

Describes a method in which glass plates are coated with adsorbent, using a technique which is cheap, rapid, and reliable; avoids the need for expensive, commercially-available thin layer chromatography equipment. (MLH)

The river was investigated at six stations from source to estuary. Modifications of water quality and aquatic communities are related to man's activities in the river basin. The organization of the exercise and the method employed are described. (Author/BB)

Methods are described for an initial survey of trampling pressure and soil compaction, and their effects on both the soil environment and the plant community structure. (Author/BB)

Proposes a method in which students teach students in preference to instruction by academic staff. (Author/BB)

Describes a first-year zoology course at University College Cardiff based on a self-instructional system using printed texts, audiovisual programs, and integrated practical work. (Author/BB)

Describes a method for teaching the technique of nearest-neighbor frequence analysis (NNFA) for testing the fidelity of template DNA replication. (Author/BB)
