The topic of refraction and reflection of light at the boundary of transparent media is a fundamentally important one. The special case of total internal reflection is however commonly misrepresented in elementary textbooks. This paper addresses the problem and describes an experimental procedure for measuring and displaying reflected and…

This study investigated the management of teaching and assessment of the "qualified to be progressed" learners (QP) for quality learning and teaching. Mixed methods approach was adopted. Random and purposive sampling were used to select teachers and School Management Team (SMT) member respectively who formed the study sample. The study…

This paper introduces the importance of middle school students' interests in learning biology. Considering the psychological characteristics of middle school students, this paper suggests several practical ways for inspiring students' interests in learning biology.

The study and construction of sundials is a useful teaching aid at several levels of instruction, since it involves understanding the shape, divisions, and major motions of the earth. (Author/RLV)

Accidentally killed animals provide biology classes with excellent study material. (Editor)

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)

Supplies short descriptions of several computer applications in the college science classroom and laboratory, including: applications; interfacing and data collection with the TRS-80; programs for activity corrections in acid/base and precipitation titration curve calculations; computer-assisted data analysis of enzyme kinetics; and microcomputer…

An experiment on sound waves, developed for non-science majors in a college physics course, is described. The student investigates the interference of two sound waves and measures and wavelength as he uses a prerecorded tape and a cassette player. The student is tutored by the cassette tape recorder, which also produces the overlapping sound…

Callus induction from species of Haworthia can be done quickly in the laboratory with minimal equipment to study tissue dedifferentiation and cellular redifferentiation. It is shown that the cultured cell can also be used to study and evaluate the effects of various mutagens, carcinogens, and pesticides in controlled environments. (Author/MA)

Microcomputers can perform two distinct functions in high school science classes, providing computer-assisted instruction and serving as tools in experimentation. This report describes a project based on three premises: that science is primarily the process of examining, modeling, and understanding nature; that the best way to learn science is by…

Discusses the use of toys to teach physics. Potential advantages and disadvantages of using toys in the physics classroom or laboratory in addition to some demonstrations and experiments that use balls, cars, and musical toys are also presented. (HM)

Presents a list of Biology-A level projects submitted for the Oxford and Cambridge Board examination by pupils of Uppingham School in the United Kingdom. (HM)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

This guide contains experiments in the fields of Physical Science, Earth Science, and Biological Science designed to be used with any series of texts in a sequence for disadvantaged youth in the middle school. Any standard classroom can be used, with minor modifications and inexpensive equipment and materials. All students could participate,…

Science activities with soap bubbles for primary school children are described in this article. Another activity involves children in determining the whereabouts of sugar as it dissolves in water. (SA)
