Adamcikova, L'ubica; Sevcik, Peter – Journal of Chemical Education, 1998
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)
Descriptors: Chemical Reactions, Chemistry, Demonstrations (Science), High Schools
Dashiell, Judy – Chemecology, 1997
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)

DeMeo, Stephen; Lythcott, Jean – Science Scope, 2001
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)

Solomon, Sally; Hur, Chinhyu – Journal of Chemical Education, 1995
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…

Laroche, Lyubov Hoffman; Wulfsberg, Gary; Young, Barbara – Journal of Chemical Education, 2003
Recommends using educational technology to present images of chemical reactions to students instead of doing time-consuming live demonstrations. Uses a VCR to show hazardous chemical reactions, give instructions to organize students into groups, think about data, draw conclusions, and design an experiment. Reports that the quality of learning from…
