Describes a series of laboratory experiments designed to provide concrete experiences with advanced inorganic chemistry lecture topics. Stresses student invention of chemical relationships and periodicity according to physical properties and reaction type. Includes comments on student performance and attitudes toward the experiments. (JM)

Describes apparatus, computer program (for Apple II), and procedures used in an experiment to determine the velocity of sound in air. In addition, the experiment focuses on the attention required in calibrating equipment and the measuring of both long distances and very short time intervals. (JN)

Three-phased learning cycles (exploration, invention, application) were introduced into general chemistry laboratories at Northland College (Wisconsin). Discusses each phase and its use in a learning cycle on the functional groups of organic compounds. (JN)

Describes use of Tinker Toys in several moment of inertia laboratory experiments at the advanced high school or introductory college levels. Includes procedures to be followed, arrangements of the Tinker Toy parts during experiments, and typical student data obtained. (JM)

Macrolab (located at New Jersey Institute of Technology) develops devices, training models, and experiments for the scientific education of handicapped students. The construction and operation of a spectrophotometer for blind and visually impaired students are discussed. Construction details are available from authors. (JN)

Describes an experiment simulating a real-life structure elucidation problem through isolation, characterization, and chemical transformation of an "unknown," naturally occurring monoterpene, with extensive use being made of spectroscopy and aided by biogenetic considerations. Information given to students, procedures, results, and discussion of…

Uses of Zenith Z-100 microcomputers by chemistry students at Clarkson College are discussed. These include: (1) programing; (2) word processing; (3) numerical methods, statistical/plotting programs; (4) laboratory data acquisition and manipulation; (5) simulations; (6) computer assisted instruction; and (7) computer managed instruction. (JN)

Describes a sixth-form field course consisting of written materials for students and a teacher's booklet giving necessary techniques, lists of apparatus, and practical hints. The course aims to estimate energy flows in a woodland ecosystem by means of a series of practical sessions involving field/laboratory investigations and calculations.…

Discusses experiments involving classical conditioning of planarians. Suitable for advanced high school students or college-level independent study, flatworms are trained to curl up under a bright light. Then the planarians to are subjected to controlled reproduction experiments to determine whether the learned behavior is inherited by their…

Describes the processes involved in clinical urinalysis and relates them to possible high school biology classroom uses. (CS)

Outlines advantages derived from constructing and using a Projectable Basic Electronics Kit and provides: (1) list of components; (2) diagrams of 10 finished components (resistor; capacitor; diode; switch; bulb; transistor; meter; variable capacitor; coil; connecting terminal); and (3) diode and transistor activities. (JN)

Examines hydraulic jumps and suggests several simple experiments which can be carried out with limited equipment. (DS)

Briefly described are 25 "hands on" classroom activities which require live, freshly killed, or preserved grasshoppers. Topics of activities include predator-prey relationships, feeding habits, locomotion, dissection, anatomy, and population estimates. (DS)

Discusses theory of the rotating mirror, its use in measuring the velocity of the electrical signal in wires, and the velocity of light. Concludes with a description of the manometric flame apparatus developed for analyzing sound waves. (SK)

An Osmette A model 5002 automatic osmometer is used to characterize different drugs, diluents, and adulterants commonly encountered in samples of forensic interest, permitting rapid determinations with good reproducibility and use by large numbers of students with little training. Includes background information, procedures, and typical students…
