Discusses modifications and special equipment needed by wheelchair-bound students for 33 common freshman physics experiments. Physical adjustments, individual needs, and personnel are addressed, with emphasis on building a rapport to learn what a student can and cannot do. A list of modifications for specific experiments (by topic) is included.…

Reviews three experiments which can be used to introduce microscale techniques. Highlights the benefits and advantages of having undergraduate students prepare and purify derivatives on the small scale. (ML)

Deals with a diffraction experiment using wrapping paper. Provides a magnified picture of the paper, a diffraction diagram, and some instructional information. (YP)

The evolution of the University of Wisconsin at Madison Interpersonal Skill Training and Research Project, which has produced 18 dissertations based on true experiments in direct social work practice, is described. Guidelines for constructing a true experiment as a dissertation are outlined. (MSE)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

Describes how short-term laboratory projects were used to teach population and community ecology to undergraduate environmental science students. Directed students to formulate and implement their own hypotheses and experimental designs. Uses questionnaire results and written reports to assess the contribution of the course to student…

Provides information appropriate for introductory lectures on photoelectric effects in membranes. Describes the apparatus and supplies required for laboratory exercises. Outlines typical laboratory exercises. Identifies the chromophores known to induce photoelectric effects. Concludes that this topic can provide useful subjects for undergraduate…

Examines the usefulness of cyclic voltammetry to the determination of a complex compound's stoichiometry. Discusses the experimental design, laboratory equipment, and results. (CW)

Presents several teaching suggestions associated with the raising of monarch butterflies in classrooms. Emphasizes how this endeavor can be used to enhance the use of science process skills. (TW)

Describes two complementary laboratory exercises that use the glass fiber assay to assess receptor specificity and hormone binding affinity in rat liver cytoplasmic extracts. Details the methods, materials and protocol of the experiments. Discusses the basic concepts illustrated and the feasibility of using the experiments at the undergraduate…

Describes an experiment to discover the topology of plasma membrane aminophospholipids (phosphatidylethanolamine and phosphatidylserine) using whole platelets and trinitrobenzene sulfonate (TNBS) as a probe. Reports changes in phospholipid distribution during platelet activation with simultaneous action of thrombia and collagen. Details the…

Describes how, using an overhead projector (OHP) and a transparent roll of acetate film, it is possible to demonstrate: (1) travelling waves; (2) standing waves; and (3) phase and group velocity applied to waves. The set-ups provide a way to demonstrate features which are normally difficult to visualize and understand. (JN)

Modeled after the program "Mastermind," this program teaches students the art of protein sequencing. The program (written in Turbo Pascal for the IBM PC, requiring 128K, a graphics adapter, and an 8070 mathematics coprocessor) generates a polypeptide whose sequence and length can be user-defined (for practice) or computer-generated (for…

Presents two simple techniques for physics demonstrations: (1) a projection lens system for oscilloscopes which uses an inexpensive surplus lens and enables the entire class to observe the screen; and (2) a polarized optical "Cheshire cat" which uses the overhead projector and Polaroid sheets. (JN)

Twenty teachers were selected to teach 20 elementary classes a science lesson featuring laboratory experience in small groups. Ten teachers were alerted to the possibilities of sexism in the physical sciences. Results indicated girls in mixed-sex work groups participate less when the teacher is less aware of sexism problems.
