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.

Paper tries to review some preliminary ideas to and underlying the setting up of an educational experiment in English as a second foreign language for children aged 10-12. (Author)

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…

Article discusses the best way to build a background of familiarity and an attitude of readiness for science learning. (Author/RK)

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)

This transition, observed with an inexpensive ultraviolet photometer, is a potentially useful experiment for an advanced freshman class because it introduces several concepts of general physical interest. (DF)

In this second article on thin layer chromatography six kinds of experiments are suggested for science teachers to use in schools. (PS)
