Describes three teaching activities used in the Chemistry for Kids program which focus on how esters are chemicals partially responsible for the flavor of foods. Includes a discussion of a demonstration involving role-playing, a set of taste tests, and an activity using chewing gum to investigate odors in food. (TW)

Describes the field work component of a half-term course in environmental chemistry. Discusses the teaching methods used with the students in detecting water pollution. Outlines the activities and experiments in one field trip and presents the results and deductions made by the students. (TW)

Presents two models and two demonstrations targeted at student understanding of projectile motion as the sum of two independent, perpendicular vectors. Describes materials required, construction, and procedures used. Includes a discussion of teaching points appropriate to each demonstration or model. (JM)

Presents chemistry experiments, laboratory procedures, demonstrations, teaching suggestions, and classroom materials/activities. These include: game for teaching ionic formulas; method for balancing equations; description of useful redox series; computer programs (with listings) for water electrolysis simulation and for determining chemical…

Presents a series of tried and tested ideas for making the college and high school biology laboratory a place where students can become active investigators. Focuses on infusing investigative laboratories into existing courses, laboratory equipment, student capabilities, instructor time, and student and instructor attitudes toward laboratory…

Outlines a variety of laboratory procedures, classroom materials, and demonstrations including a demonstration of the Markownikoff rule; blue bottle reaction and photosynthesis; a cheaper version of Fehling's solution; chemical formulas for younger students; chemical bonding and periodicity cards; optical activity demonstrations; and six others.…

Provided is an empirical method to train students to avoid physical disaster in their work experience. Discussed is a computer program, CHETAH, which can be used in advance of synthesis to classify the possible explosive nature of the products. Plosophoric and auxoplosive weights of many organic groups are listed. (MVL)

Described are three chemistry demonstrations: (1) a simple qualitative technique for taste pattern recognition in structure-activity relationships; (2) a microscale study of gaseous diffusion using bleach, HCl, ammonia, and phenolphthalein; and (3) the rotation of polarized light by stereoisomers of limonene. (MVL)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)

Describes a demonstration showing the chemical reversibility between the chromate and dichromate ions. Includes reaction equations and listing of equipment needed. Recommends a demonstration for illustrating Le Chatelier's principle and stoichiometric relationships. (ML)

Examines a solubility laboratory experiment using silver acetate and spectrophotometers for an Advanced Placement chemistry course. Covers experimental procedure, analysis of saturated solutions, and a discussion of chemistry involved. Includes an absorbance curve for silver ions and solution preparation suggestions. (ML)

Discusses how, in two three-week sessions, the Terre Haute (Indiana) college offers selected students a hands-on approach to all aspects of engineering from design and lab work to technical writing. Describes a group project requiring students to study and experiment with simple research problems. Lists 20 project ideas. (MVL)

Presents a course outline for the study of biotechnology at the high school or college level. The outline includes definitions, a history, and the vocabulary of biotechnology. Presents a science experiment to analyze the effects of restriction enzymes on DNA. (MDH)

Describes an extra credit science project in which students compete to see who can build the most efficient water rocket out of a two-liter pop bottle. Provides instructions on how to build a demonstration rocket and launching pad. (MDH)
