Describes a science laboratory experiment that can be done at home with the assistance of parents or older siblings. It is offered as an alternative to reading assignments or answering questions for homework. Parental assistance is encouraged. (SA)

Described is independent study research at Garden City High School (Garden City, NY) involving ten students studying seasonal beach erosion, salt marsh preservation, sludge leachate hazards in bays, and sewer outfall effects on barrier bays. Outcomes include better understanding of the scientific process and careful, accurate research. (Author/DS)

Describes a transfer device for fruit flies based on the upward movement of fruit flies. Includes instructions for constructing the apparatus. (CS)

Presents the results of a survey on the status of inorganic laboratory courses. Indicates that they are in a continuing period of evolution and all stages of the evolution are represented in schools across the country. (Author/JN)

Some simple undergraduate laboratory experiments are described, which verify the energy-momentum relationship of special relativity. These experiments have been designed either to be used as classroom demonstrations or to be carried out by second-year students. (Author/JN)

Describes an exercise using dandelion floral stems to demonstrate the movement of water through cellular membranes. (CS)

Samples of materials available to students from grades 4 through 12 at a Mathematics Center are reviewed. The examples are part of a collection of more than 200 mathematical tasks using solid materials in a new approach to problem solving. (MP)

Proposes that more accurate and persistent learning results from programs which permit students to interact with their environment and that the addition of relevant direct and vicarious experiences can lead to improvements in the learning which takes place in traditional academic courses. (JD)

Described is the use of two models of pocket calculators. The Hewlett-Packard HP67 and the Texas Instruments TI59, to solve problems arising in connection with ionic equilibria in solution. A three-parameter regression program is described and listed as a specific example, the hydrolysis of hexavalent uranium, is provided. (BT)

Describes a simple, inexpensive Faraday balance for studying the effect of a strong magnetic field on selected reaction rates. Aschematic diagram detailing the essential features is included. (BT)

Instructional strategies are described for a one-year program at the University of Washington which attempts to increase the number of minority students being admitted to health science professions. The strategies focus on the necessity of the laboratory, reasoning ability, examinations, and homework. (Author/SA)

The rationale for equalizing the pay scale for laboratory and lecture teaching in two and four year colleges is presented. (Author/SA)

Describes three accessories developed to be used in conjunction with the rotating platform or turntable. Three demonstrations using these accessories are included. These demonstrations are: (a) conservation of angular momentum; (b) gravity-defying goblets; and (c) direct measurement of centripetal force. (HM)

Presents two methods for measuring the index of refraction of glass or lucite. These two methods, used in the freshman laboratory, are based on the fact that a ray of light inside a block will be refracted parallel to the surface. (HM)

Discusses a study undertaken to assess the effect of graduate student teaching assistants on undergraduate students' attitudes toward psychology in an introductory psychology laboratory course. Findings indicated that good TAs convey more positive feelings about the labs than do poorer TAs. (DB)
