To involve students in thinking about the problem of AIDS (which is important in the view of nondecreasing infection rates), we established a practical lab using a simplified adaptation of Thomas's (2004) method to determine the polymorphism of HIV co-receptor CCR5 from students' own epithelial cells. CCR5 is a receptor involved in inflammatory…

Includes methods for determining melting and boiling points, illustrating the Finkelstein reaction, choosing acid-base indicators, growing perfect NaC1 cubes and "whiskers," bromination of alkenes, using vanadium in the laboratory, preparing phenylamine-copper (II) sulfate (VI) complex, simulating first-order chemical kinetics on a programmable…

Includes methods for demonstrating Schlieren effect, measuring refractive index, measuring acceleration, presenting concepts of optics, automatically recording weather, constructing apparaturs for sound experiments, using thermistor thermometers, using the 741 operational amplifier in analog computing, measuring inductance, electronically ringing…

Includes methods for using harmonographs in demonstrating motion of pendulums, constructing an electrostatic "bell," inverting mirror images, demonstrating the corrosion rate of steel, demonstrating expansion, studying rate of reaction between magnesium and hydrochloric acid, using matchboxes in science for containers, problem boxes, building…

Includes procedures for demonstrating anaerobic respiration in peas, isolating virgin Drosophila females, solving mortality problems in young gerbils, measuring dissolved oxygen, constructing models for transpiration and DNA molecules, freezing chick embryos, mixing nutrient media, illustrating Darwinian ecological principles, and detecting…

Describes an activity using simple materials that gives students an opportunity to express their ideas about possible extraterrestrial life forms. (JR)

Describes how student understanding and interest in the metric system system can be stimulated by building and launching model rockets. (JR)

Described is an investigation of the contributions of genes and environment to a quantitative character using readily available varieties of dwarf beans. Included are a list of materials, typical results, and a student instruction sheet. (CW)

Activity suggestions for the months of September and October are provided in a calendar format. In addition, two activity sheets, which provide detailed information for studying the moon and the alphabet including materials, and procedures are provided. (CW)

Presented are several ideas for projects involving ladybird beetles. Discussed is background information about the insects; and projects involving life histories, intra-specific variation, taxonomy, genetics, behavior, ecology, habitat surveys, population biology, and overwintering biology. Lists 12 references. (CW)

This paper shows that more pupils take biology than the other sciences in England. Biology attracts pupils of all abilities and girls in particular. Performance data reported suggests that the study of biology is not as effective in enhancing science performance as are the physical sciences. (CW)

Two designs of undergraduate terrestrial ecology and behavior field courses are described and compared. These include using a variety of projects and using a single individual research project. The relative educational benefits of each are considered and the advantages of each type of course are discussed. (Author/CW)

Presented is a guide for students planning to do a science project. Discussed are preliminary organizational matters, report plans, choosing topics, setting up procedures, time management, and documentation. The most important steps for producing a successful project are summarized. (CW)

Described is a 35mm projector demonstration which combines the advantages a highly magnified view of the sample zone as it undergoes dispersion and the ability to show more than a single-line flow injection analysis manifold. Manufacture and use of the slide for demonstration are discussed. (CW)
