Describes a sea-water analysis project that introduces qualitative and quantitative analysis methods and laboratory methods such as gravimetric analysis, potentiometric titration, ion-selective electrodes, and the use of calibration curves. Uses a problem-based cooperative teaching approach. (Contains 24 references.) (YDS)

Presents a scenario of a plane crash and asks students to identify passengers based on chemical compounds and passengers' health conditions. (YDS)

Presents an activity that explores the temperature behavior of UV-sensitive beads and investigates the effectiveness of sunscreens. (ASK)

Introduces a laboratory experiment for determining blood alcohol content using a combination of instrumental analysis and forensic science. Teaches the importance of careful laboratory technique and that experiments are conducted for a reason. Includes the procedure of the experiment. (Contains 17 references.) (YDS)

Explains the theory of thin layer electrophoresis, hazards related to the apparatus, and how to conduct an experiment. (YDS)

Describes pigments and artists' colors from a chronological perspective. Explains how chemical analysis can be used to distinguish the differences between artists' palettes, identify the evolution of art, and lead to restoration of an art work. (Contains 13 references.) (YDS)

Describes a laboratory experiment in which students identify 11 white solids readily available in drugstores and supermarkets. Investigates solubility, pH, copper reduction, evolution of carbon dioxide bubbles, formation of starch-iodine complex, and formation of an insoluble hydroxide. (YDS)

Describes a laser refractometry experiment to estimate the refractive index of various liquids. (YDS)

Introduces a chemical Sherlock Holmes mystery story based on properties of biological substances and qualitative analysis. (YDS)

Presents a story of a footrace between different groups of people that can be used to teach about chemical separation by chromatography. (WRM)

Presents an activity that is a qualitative version of the standard paper chromatography experiment. This activity introduces students to methods of selecting the best solvent for a separation and allows them to consider the effects of adding acid and base. (WRM)

Introduces electrophoresis activities developed for chemistry and biology courses in which students identify the food, drug, and cosmetic identity of the food dyes used in the coating of candies. (YDS)

Presents a laboratory experiment in which students study the sampling of solids and statistical analysis. (YDS)

Reports on a community-service project carried out by general chemistry students at the University of Utah. Students research lead poisoning then visit neighborhood homes to teach about lead poisoning, collect exterior paint samples, and analyze them as part of a chemistry experiment. Discusses service-learning and laboratory activities. (WRM)

Describes a series of exercises intended to help students develop a better understanding of chromatography that employ plant pigments. A collaborative approach leads students to a level of competence that permits them to complete an open-ended exercise. (WRM)
