A description of the film loop laboratory system as an attempt to increase the desirability, flexibility, and efficiency of physics experiments for non-science students. (Author)

Includes thirteen topics relating to laboratory activities, organisms, and teaching materials for secondary school biology classes. Also provides a reading list of articles published during 1972 that are suitable for A and S level biology. (JR)

Describes the measurement of electric potentials by means of a flame probe. This method is used extensively in the new Nuffield Advanced Level Physics course, and provides a means of taking reliable quantitative results in an area of most school courses where the majority of the work is qualitative. (JR)

Describes a course based on three levels of student performance (achievement, rationalization, creative). Students work on the achievement level at their own rates with lectures available, but not mandatory. Laboratory exercises are required. Grading is dependent on the amount of fulfillment of all three levels. Year-end assessment was determined…

Describes various techniques for conical chromatography together with advantages and disadvantages. (DF)

Twelve new experiments in biology are described by teachers for use in classrooms. Broad areas covered include enzyme action, growth regulation, microscopy, respiration, germination, plant succession, leaf structure and blood structure. Explanations are detailed. (PS)
