Describes a chemistry demonstration on freezing point depression wherein students investigate the effects of adding various substances to ice water. Includes instructor information and a student activity sheet. (YDS)

Describes a series of simple but spectacular chemistry demonstrations designed to capture children's imaginations. The demonstrations take the minimum amount of time to prepare, are relatively safe to dispose of, and reliable. (Author/WRM)

Describes the benefits of a program in which female undergraduate science majors conduct chemistry demonstrations for middle-school students. Finds that undergraduate women serve well as mentors to middle-school girls. (WRM)

Explains a way of observing pattern formation in the Blue Bottle chemistry demonstration by pouring a solution containing sodium hydroxide, glucose, and dye into a Petri dish and placing the dish on an overhead projector. (WRM)

Describes a program initiated by a high school chemistry teacher in which high school honors chemistry students do chemistry demonstrations for local elementary school students. The program has had great success in sparking enthusiasm and interest in chemistry among both high school and elementary school students. (DKM)

Encourages the incorporation into lecture of live experiments that can be predicted or interpreted with abstract models. A demonstration is described where the position of the predominant peak of 1,1'-diethyl-4,4'-cyanine iodide is measured in class using an overhead projector spectrometer, then predicted using the model of a particle in a…

Presents a science experiment to demonstrate the emergence of a snake from an "egg" and illustrates the necessity of heat to induce the hatching process. (MKR)

Describes a novel demonstration of the acid-base chemistry of the aluminum ion. (DKM)

Summarizes ideas for new demonstrations, experiments, and science-in-society topics for teaching chemistry. (WRM)

Describes procedures for a demonstration that features an exploding can. This demonstration prompts students to critically analyze the release of energy in an exothermic reaction, the work done in such a reaction, and the enthalpy. (DDR)

Demonstration of chemical reactions is a tool used in the teaching of inorganic descriptive chemistry to enable students to understand the fundamental concepts of chemistry through the use of concrete examples. For maximum benefit, students need to learn through discovery to observe, interpret, hypothesize, and draw conclusions; however, chemical…

Describes a demonstration of static charge using balloons and crystals to illustrate the electrical nature of matter. Building on the classic physics demonstration that uses pieces of paper and a plastic rod, this approach adds a new dimension of chemistry. Offers suggestions for how to discuss the observed phenomenon. (DLH)

Describes the recent history, chemistry, and educational uses of the Orange Juice Clock demonstration in which a galvanic cell is made from the combination of a magnesium strip, a copper strip, and juice in a beaker. Discusses the chemistry basics, extensions for more advanced students, questions for student/teacher workshop participants, and…

Describes an outdoor scientific demonstration of metal reduction, a reaction known as the thermit process. Heat from an ignition mixture is required to initiate the reaction, which then becomes self-sustaining. The demonstration provides a dazzling introduction to such fundamental general chemistry topics as oxidation-reduction, metallurgy,…

Describes a chemistry course with the goal of fostering a broader and deeper understanding of a few fundamental concepts through group discussion, instructor exposition, and participant-developed laboratory and demonstration activities. (DDR)
