Presents four stoichiometric problems and their solutions that use spot metal prices quoted from the newspaper to integrate economics and chemistry. (MDH)

The outline for a unit on the chemistry of fitness and nutrition is presented. Topics discussed include the organic basis of life, functional groups, kitchen experiments, micronutrients, energetics, fitness vs. fatness, current topics, and evaluation. This unit reviews the basic concepts of chemical bonding, acid-base chemistry, stoichiometry, and…

Discussed is the Scope, Sequence, and Coordination science curriculum in which students study a combination of biology, chemistry, physics, and earth/space science over a six-year period. The implementation of this curriculum in various schools is described. (KR)

Illustrated is the use of spreadsheet programs for implementing finite difference numerical simulations of chromatography as an instructional tool in a separations course. Discussed are differential equations, discretization and integration, spreadsheet development, computer requirements, and typical simulation results. (CW)

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) is reported. MANOVA results indicate significant difference between expert and novice students solving the five stoichiometric chemistry problems using…

Describes an activity in which students examine hypothetical exposure to toxins by being showered by different colored pieces of confetti over several visits to exposure sites. Students record quantities of confetti that stick to packing tape. Colors correspond to different toxins posing different health problems. Students process their findings…

Describes a course-integrated approach to library instruction for chemical information at the University of Florida that uses a Web page of library resources with links to library instruction modules and assignments. Implications for library staff, library resources, and the role of the library are discussed. (LRW)

Discusses chemical information services offered in industrial chemical libraries, based on experiences at the 3M Library. Topics include qualifications of chemical information professionals; corporate culture; clients; services, including reference, current awareness, confidentiality, and end-user support; and information resources, including…

Describes a teacher-researcher's investigation into barriers to student adoption of an alternative referent for learning and its consequential learning strategies in an 11th-grade chemistry class. Suggests that various contextual factors influenced students' willingness to adopt the alternative referent, and that students' beliefs, trust of the…

Investigates the relationship between students' achievement expectations and academic self-concept and their subsequent achievement in college chemistry. Findings suggest that students' academic self-concept and achievement expectations are significant predictors of overall grade performance whereas prior achievement was the only significant…

Summarizes several articles on safety in the science laboratory, an article on the science and history of chocolate, and an article on teaching nuclear physics from an historical perspective. (WRM)

In this article, the author discusses "The Biology of Food" course. This course--a large lecture course with no laboratory section--is a mixture of kitchen chemistry, post-eating food metabolism, origins of different foods (from crop breeding to evolution), and ecological and environmental impacts of farming and harvesting practices. Nearly every…

Inquiry can be implemented in various ways, ranging from simple classroom discussions to longterm research projects. In this article, the authors developed a project in which high school students were introduced to the nature and process of scientific discovery through a two-week guided inquiry unit on "limnology"--the study of fresh water, which…

Four different team teaching experiences are described with collaborators from a variety of disciplines. The pedagogical differences between the teachers created unique challenges. A description of each collaboration is provided, followed by an analysis of the four experiences. An examination of the challenges that arose are summarized to…

The effect of intervening use of molecular visualization software was tested on 73 first-year general chemistry students. Pretests and posttests included both traditional multiple-choice questions and model-building activities. Overall students improved after working with the software, although students performed less well on the model-building…
