Summarizes workshop notes on the use of a variety of test dipsticks to determine qualitative and quantitative aspects for several common food items. Discusses availability, tests, and uses for these dipsticks: Merckoquant, Clinistix, and Multimix. (CS)

Describes an advanced inorganic experiment employing the Faraday magnetic susceptibility system. (CS)

Describes the use of an inflatable planetarium, the STARLAB, in teaching astronomy to elementary school students. (SA)

Described is a science program for students in grades 3 and 4. Because there is only one hour per week set aside for science instruction, an attempt has been made to incorporate science into other subject areas. (KC)

Lists eight guidelines for the use of live animals at the pre-university level adopted by the National Association for Biology Teachers in March 1980. (CS)

Presents applications in (1) radiochemistry by using experimental data from earthquakes, and (2) Boyle's Law by the opening of beer cans. (CS)

Describes a method suitable for quantitative studies of plant water status conducted by high school or college students and the calculation of the relative water content (RWC) of a plant. Materials, methods, procedures, and results are discussed, with sample data figures provided. (CS)

A group of teachers' advisers and college tutors became interested in developing some "safe" science activities for junior high school physically handicapped students. A series of pacakage experiments on approximately 30 scientific principles were tested for potential drawbacks for the handicapped child. Several experiments are described. (SBH)

Presents results of a two-year study regarding factors causing student difficulties in performing investigative activities in a beginning biology course. Also investigates the usefulness of written guidelines in alleviating these difficulties. A model for student investigations is proposed. (CS)

Reports a study conducted to determine how students cope with a procedureless laboratory situation in physical chemistry. Students are expected to use ingenuity, determine choice of sample size, conditions, and temperature extrapolation in an experiment on measuring heat of solution of an unknown salt. (Author/SA)

Describes how the home toilet tank can be used as either a classroom problem or experiment that provides a simple introduction to process control. (HM)

Describes a physical chemistry laboratory experiment that illustrates the concepts of inductive and resonance effects by the calorimetric determination of the heats of protonation of pyridine, 2-chloropyridine, and 3-chloropyridine. (CS)

Provides instructions for planting a variety of common plants including avocados, and sweet potatoes, oranges, and onions. Discusses key concepts to develop. (MA)

Describes taste experiences that are used to spark interest in studying high school biology. Emphasizes learning about survival, poisonous plants, endangered species, economic and nutritional importance of various organisms, and cultural education. (CS)

Describes how to construct a thermometer from a ballpoint pen; how to illustrate standing waves with pocket combs; and various physics demonstrations using oval panty hose containers. (MLH)
