Describes a sophisticated version of the fruit fly experiment for teaching concepts about genetics to biology students. Provides students with the opportunity to work with live animals over an extended period. (JRH)

Discusses strategies to duplicate current research protocols using biochemical methods of analysis. Describes the use of the Silver Sequence kit that provides a technically simple and relatively inexpensive DNA sequencing exercise. (JRH)

Describes a bioassay laboratory exercise designed to introduce students to both acute and chronic bioassay procedures. Reinforces ecological principles and provides opportunities for students to use knowledge learned in the classroom in a realistic and ecologically-relevant situation. Contains 11 references. (JRH)

Demonstrates the differences in protein structures by focusing on isoelectric point with an experiment that is observable under certain pH levels in gel electrophoresis. Explains the electrophoresis procedure and reports results of the experiments. (YDS)

Introduces a brine shrimp assay to demonstrate the effects of the biological activity of herbal remedies. Describes two protocols, one using aqueous extracts and the other using methanol extracts. (Contains 21 references.) (YDS)

Describes a microbiology laboratory experiment in which students test their own microbial flora of Staphylococcus for antibiotic resistance. Provides directions on how to conduct the experiment. (YDS)

Determines that the philosophical basis for science education is likely to be an interesting field in the 21st century and that there is a need to provide the practicing teacher with some ideas for daily work such as local, national, and international student cooperation; using student lab reports to develop local scientific journals; and having…

Introduces a student activity that explains acid base reactions with a carbon dioxide reactant. Includes both instructor information and student activity sheet. (YDS)

Explores the dominant factor controlling the distribution of Daphnia. Describes components of a temperature gradient apparatus that can be assembled from materials readily obtainable in the laboratory and hardware stores. Investigates whether the mean depth of Daphnia is determined by temperature. (KHR)

Describes an automatic pipette washer that is functional, inexpensive, and easy to construct from locally available parts. (KHR)

Describes an experiment that introduces students to the different types of UV rays and their effects on living things by using appropriate teaching materials and equipment. Demonstrates the effects of exposure to UV-B (fluorescent) and UV-C (germicidal) lamps by using bananas, duckweed, and the fruit fly. (Contains 14 references.) (Author/YDS)

Used two experiments to assess extent to which introductory psychology students' self-selection into experiments produced biased samples. Students chose between apparently different experiments with different descriptions and between individual and group sign-up slots. Results demonstrated that students sorted themselves into experiments and into…

Introduces three demonstrations using rubber balloons: rate of reaction, air pressure, and solubility of gases in liquids. Provides the materials, procedure, questions, further investigation, and discussion in each demonstration. (YP)

This article describes the basic physics of several types of holograms and discusses different recording materials in use. Current and possible future applications of holograms are described as well as their large-scale production. (Author)

Although all students need more and better science classes to face the next century's challenges, students gifted in science also need access to dedicated teachers willing to assist their learning progress and encourage their production of original research projects. Integrating the science curriculum would also benefit gifted and other students.…
