Provides procedures and comments for 15 short chemical experiments suitable for classroom demonstrations or public displays about chemistry. (MLH)

This book presents science activities investigating the chemical changes and reactions with powders that are used in baking. Activities include: (1) Mystery Powders; (2) Find the Fizz: Discover the Secret of Baking Powder; and (3) A Feast for Yeast and Cheese: Behold the Power of Chemistry. (YDS)

Presents a teaching strategy to successfully teach the periodic table using nuts and bolts as elemental analogs. Describes activities that enable the student to develop a deeper understanding of the periodic table and how it is organized. (JRH)

Describes a technique that can be used to develop accuracy, precision, and a neat laboratory approach in the student. The technique can also be used to demonstrate the stoichiometry of a reaction. (GS)

Describes the science of hair analysis and its use in the solution of crimes. Methods of analysis and genetic and environmental characteristics which can be inferred are presented. (CP)

Described is a student preparation of YBa2Cu3O8-x, a classroom demonstration of its superconductivity, and an analytical chemistry experiment dealing with the oxidation state of copper in the material. (RH)

Described is a workshop for grades 5-8 school teachers and students related to synthetic polymers. Participants become familiar with polymer theory and practice experiments they can use in class. Sources of materials used in the workshop are listed. (RH)

Presents activities that use a simple homemade apparatus called "the cannon" to demonstrate Newton's Third Law. Reviews the chemistry concepts behind the ignition of the cannon and presents the Momentum Lab and the Projectile Motion Lab. (JRH)

Presents an assignment that involves forming student companies to determine and defend cost estimates for producing a silver Oscar statuette. Includes an assessment rubric for cooperative effort. (JRH)

Presents an activity to investigate soil nitrification and denitrification. Enables students to visualize the transformation of ammonium to nitrate and its reduction to nitrogen gases. (JRH)

Presents an activity exploring the basics of atomic structure using the theme of the Addams Family. (MKR)

Describes the use of carbide lights as an excellent mechanism for introducing or reviewing many basic chemistry concepts including elements and compounds, endothermic and exothermic reactions, physical and chemical changes, and balancing chemical equations. (JRH)

An explanation of the difference between the terms isosmotic and isotonic, and an experiment to demonstrate this difference are presented. (BB)

Described is the use of calculators in two experiments. In the first, students determine the relative atomic mass of magnesium. In the second, students use a calculator to determine a constant for gaseous concentrations of two reactants and the product at equilibrium. (AJ)

Provides an activity using concrete examples to help students understand Dalton's atomic theory and explore its link to finding empirical formulas. (ZWH)
