Reviews three audiovisual instructional aids, providing information on time, format, catalog number, price, and supplier. "Distillation: Simple and Fractional,""The Periodic Table," and "Manmade Macromolecules" are considered to be excellent materials for secondary school chemistry classes. (JN)

Compared student attitudes (N=211) toward chemistry/mathematics. Results indicate no significant differences between liking a subject and its importance or application, with mathematics being seen as more important and more useful than chemistry. Suggests that teachers must spend more time and energy in developing positive attitudes toward…

Describes a safety program adopted by Southeastern Louisiana University. Students are given detailed instructions on laboratory safety during the first laboratory period and a test which must be completely correct before they are allowed to return to the laboratory. Test questions, list of safety rules, and a laboratory accident report form are…

Discusses research indicating that presenting students with large amounts of information while their concepts are primitive prevents them from grouping/handling the very information they need to make concepts develop. Reducing the load or providing strategies to help students group/sequence the load are recommended. (JN)

Describes a method used to define major areas in individualizing a high school chemistry course and modules that emphasize competency in investigative process skills, basic concepts, and reading comprehension for each module. Includes flow chart of modules, flow chart of student learning path, and a sample module on electron clouds. (JN)

Presented are procedures for demonstrating the production of color oscillations when nitric acid is added to a formic acid/concentrated sulfuric acid mixture. Because of safety considerations, "Super-8" home movie of the color changes was found to be satisfactory for demonstration purposes. (JN)

Out of 70 answers to questions concerning the chemistry involved in an "orange tornado" demonstration, only 10 were partially correct, others totally wrong or showing major errors in understanding, comprehension, and/or reasoning. Demonstration and reactions involved, selected incorrect answers, and a substantially correct answer are discussed.…

Choice Chemistry is a multi-level course written in a style for use in Scotland (but adaptable for other areas). Underlying course philosophies (including mastery/personalized learning approaches), course structure, and course content are discussed. (JN)

Discusses three methods for removing wastes from educational laboratories. These include paying someone with Environmental Protection Agency (EPA) permits, doing part of the work before an EPA contractor carries out final steps, or reducing magnitude of future disposal problems by changing present laboratory procedures. Includes comments on…

Discusses a supplement to the "water to rose" demonstration in which a pink color is produced. Also discusses blood buffer demonstrations, including hydrolysis of sodium bicarbonate, simulated blood buffer, metabolic acidosis, natural compensation of metabolic acidosis, metabolic alkalosis, acidosis treatment, and alkalosis treatment. Procedures…

Conductiometric titrations can be used to simulate subduction-setting volcanism. Suggestions are made as to the use of this technique in teaching volcanic mechanisms and geochemical indications of tectonic settings. (JN)

Electrography is a technique in which unknown metals are identified by the precipitates they form with known electrolytes. The technique illustrates both electrochemistry and precipitation reactions. Describes the technique, suggesting its use in science and forensic science classes. (JN)

Describes activities (demonstrations/experiments) used to introduce history of periodic properties--without electrons, orbitals, filling shells, or any conception of atoms beyond Dalton's model. Activities supplement first chapter in a currently available chemistry text. Indicates potential danger of experiments if proper safety precautions are…

Presents an experimental comparison of the efficacy of two neutron sources under conditions commonly used in laboratory experiments for demonstrating neutron activation of liquid samples. (Author)
