Presents activities that integrate physics, earth science, and health. Students explore their own sensible temperature focusing on the physical processes of heat transfer. (DDR)

Presents information about the chemistry of color-changing markers. Discusses the importance of acid-base reactions and oxidation-reduction chemistry. (DDR)

Describes an inquiry-based scooter activity in which students learn the mathematical concepts of measurement and proportionality and the science concepts of force, motion, velocity, and acceleration while using their problem solving skills. Explains strengths and weaknesses of the activity and includes suggestions for assessment. (YDS)

Described is a classification activity that uses holiday greeting cards. Identification of animals, their characteristics, natural habitat, eating patterns, and geography are some of the suggested ways in which to classify the animals. (KR)

Reported are the results of a survey of undergraduate students regarding their attitudes about the use of animals in science experiments following a presentation of both sides of the issue. Survey methods, results, and implications are discussed. (CW)

Described is a solar science activity designed to show students how light energy can be directed to produce visible chemical changes by making sunprints. Included are the materials, procedure, and safety considerations. (KR)

Described is a team assignment where groups of students work on stoichiometry problems that apply to the real world. Teams of students act as chemical companies that have orders to fill for a customer. Included are the details of the customer order, student participation, and the evaluation procedure. (KR)

Described is a guided "fantasy" to help students explore ocean-related ecological concepts. The concepts of natural camouflage and predator/prey relationships are illustrated by activities. (KR)

Presented is an activity that may be used to help students clarify the basics of graphing while allowing individuals to collect data and perform a simple experiment. A timetable, rules for graphing, materials, procedures, and suggestions for extension activities are provided. (CW)

Described is a simple and interesting chromatography experiment using three different fluorescence detection principles for the determination of caffeine, saccharin and sodium benzoate in beverages. Experimental procedures and an analysis and discussion of the results are included. (CW)

Presented are the procedures and a discussion of the results for an experiment in which students select unknown carboxylic acids, determine their melting points, and investigate their solubility behavior in water and ethanol. A table of selected carboxylic acids is included. (CW)

Described are some of the considerations necessary in planning a field studies course in the tropics. Discussed are site selection; planning and preparation; course structure; the advantages of travel courses; and recommendations concerning liability, multiple instructors, hotels, sailboats, and tours. A list of 26 references is included. (CW)

Presented are arguments for the use of a case study approach for the teaching of human heredity. The design of case studies and related exercises is discussed. Five examples are given. A list of eight resources for case study samples is included. (CW)

Considered is an experiment used to investigate one-dimensional, nonuniform acceleration. Presented is the correct expression for the acceleration, generalized to include friction and describe simulations supporting student data. The feasibility of the experiment is questioned. (CW)

Described is a project involving the introduction of microcomputers into the laboratory portion of a college general physics course for data collection and analysis. The results of an evaluation of this program are presented. (CW)
