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

Introduces a project incorporating creative writing and advanced placement chemistry. Uses texts and laboratory experiments for the basis of the writing assignments. (YDS)

Explains an oxidation-reduction experiment using lemon cells made from zinc and copper strips of metal placed into a lemon. (YDS)

Describes two strategies for implementing active learning in physical chemistry, one involving supplementing the traditional lecture course with heavily computer-based active learning exercises carried out by cooperative groups, the other using cooperative learning almost exclusively supplemented by occasional mini-lectures. Both approaches seemed…

Presents an activity that demonstrates the effectiveness of flame retardants--substances added to combustible materials to slow down or hinder burning--that can be introduced when discussing combustion reactions or during a practical or everyday chemistry unit. (ASK)

Flame tests are used for demonstration of atomic structure. Describes a demonstration that uses spray bottles filled with methanol and a variety of salts to produce a brilliantly colored flame. (Contains 11 references.) (ASK)

Electrochemiluminescence involves the production of light near an electrode surface by generating species that can undergo highly energetic electron transfer reactions. Presents a demonstration that uses Ru(bpy)32+ (bpy = 2,2'-bipyridine) as the light-emitting molecule and tri-n-propylamine (C9H21N) as a coreactant. (Contains 25 references.) (ASK)

Previous research has shown that students often have multiple conceptions within any particular topic area in science, and these conceptions are usually strongly linked to specific problem situations or contexts. Investigates the nature of any possible relationship between these conceptions. (Author/MM)

Introduces a learning module integrating three disciplines--physics, chemistry, and biology--and based on four elements: carbon, oxygen, hydrogen, and silicon. Includes atomic model and silicon-based life activities. (YDS)

Describes how to adopt a Science Writing Heuristic (SWH) in an introductory college chemistry laboratory to promote a more positive attitude in students and better conceptual understanding of laboratory reports. (Author/MM)

Discusses the importance of environmental chemistry and the use of laboratory exercises in analytical and general chemistry courses. Notes the importance of lab work in heightening student interest in coursework including problem-based learning in undergraduate curricula, ready adaptability of environmental coursework to existing curricula, and…

Presents an activity that is suitable for a high school chemistry or introductory college chemistry lab in which students create their own Fizzie-style carbonated beverage and use stoichiometry to calculate the correct mix of citric acid and baking soda. (Author/ASK)

Presents an activity on building a structure with Lego blocks and points out the importance of laboratory records. Includes instructor information and a student worksheet. (YDS)

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

For over a decade, the authors have been involved in a design theory experiment providing software for high school students preparing for the descriptive question on the Advanced Placement (AP) chemistry examination. Since 1997, the software has been available as a Web site offering repeatable practice. This study describes a 4-year project during…
