Discusses the issues involved in creating an Internet-based chemistry class, including presentation of material, testing, lab work, and administrative support. (WRM)

Describes a study that investigated the relationship and development of fifth-grade students' conceptual ecologies of heat. Contends that relying on a single mode of assessing students' learning can lead to a restricted view of what they truly know. (WRM)

Contends that an established collaboration with a local resource--whether it be a university or trained professionals from local industry--can enhance the enthusiasm, resources, and experimental design of science fair projects. Describes the nature of some interactions related to a high school science fair and details some successful student…

Describes the construction of an exponential decay graph that can be used in a science class to support discussions about the uses of radioactivity, its risks, limitations, and advantages. (WRM)

Presents instructions for building a simple interactive unit-cell construction kit that allows for the construction of simple, body-centered, and face-centered cubic lattices. The lit is built from inexpensive and readily available materials and can be built in any number of sizes. (WRM)

Describes some simple experiments related to the properties of crystals. Illustrates isomorphism using single crystals of alum. Presents experiments for determining how various mixture compositions affect the growth of salt crystals. (WRM)

Provides an anthology of references to descriptions of analytical chemistry techniques from history, popular fiction, and film which can be used to capture student interest and frame discussions of chemical techniques. (WRM)

Describes a scientific mystery with an emphasis on chemical magic presented in the context of the characters Sherlock Holmes and Dr. Watson. The story contains a break where students and teachers pause to ponder and solve the mystery. Sherlock Holmes provides his solution in the paragraphs following this break. (WRM)

Suggests that simple riddles can be used effectively to make students interact in science class. Proposed teaching methods require the student to provide answers to riddles in order to develop the discussion about a given topic. Presents sample riddles related to elements and their compounds. (WRM)

Describes a teaching technique of playing BINGO to simple alkane nomenclature and many possible variations. (WRM)

Describes two related color-change reactions that are relatively easy and safe to demonstrate. In the "Sunday School Reaction", a black and a white solution are mixed to form a white solution. In the "South Africa Reaction", a series of black, brown, red, and white solutions are mixed to form a clear, colorless solution. (WRM)

Describes how to grow crystals of para-dichlorobenzene beginning with household mothballs. The crystals form through sublimation (solid to gas) and deposition (gas to solid). Also discusses demonstrations of evaporation and condensation and odor perception, which can support a study of the kinetic theory and phases of matter. (WRM)

Describes a study that sought to provide a better understanding of "chemophobia" at the college level by determining the extent of chemophobia in the college classroom, the factors that contribute to college students' fear of learning chemistry and handling chemicals, and the characteristics of college students who display these fears. (Contains…

Presents an activity that can be used for acid-base chemistry, everyday chemistry, or food chemistry. Investigates the rising in baked goods. Includes both instructor information and student activity sheets. (YDS)

Introduces the ATOFINA Science Teacher Program, developed with the cooperation of industry and focusing on the professional development of elementary school science teachers as the first step toward developing a scientifically literate population. (YDS)
