Peer reviewedHollenberg, J. Leland – Journal of Chemical Education, 1979
The theoretical basis for the calculation of hydration numbers is developed. (BB)
Descriptors: Chemical Bonding, Chemistry, College Science, Computation
Peer reviewedMeyer, Edwin F.; Meyer, Thomas P. – Journal of Chemical Education, 1986
Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)
Descriptors: Chemical Equilibrium, Chemistry, College Science, Computation
Peer reviewedMichaelis, M. M.; Haines, C. M. – Physics Education, 1989
Describes several ways to partially levitate permanent magnets. Computes field line geometries and oscillation frequencies. Provides several diagrams illustrating the mechanism of the oscillation. (YP)

Vanfield, Grant – SASTA Journal, 1979
Presents a science project involving the production, transportation, handling and preparation of food for human consumption. Calculations of caloric value of the food intake and the energy costs of cooking are included. (Author/SA)
Descriptors: Computation, Energy, Environmental Education, Food Service
Peer reviewedCardinali, Mario Emilio; Giomini, Claudio – Journal of Chemical Education, 1989
Proposes a simple procedure based on an expansion of the exponential terms of Raoult's law by applying it to the case of the benzene-toluene mixture. The results with experimental values are presented as a table. (YP)
Descriptors: Chemistry, College Science, Computation, Equations (Mathematics)
Peer reviewedGeorge, Arnold – Science and Children, 1992
Describes four activities to analyze drinking water for its pH, hardness, turbidity, and conductivity. (MDH)
Descriptors: Chemistry, Computation, Drinking Water, Elementary Education
Peer reviewedRamirez, Santos A.; Ham, Joe S. – Physics Teacher, 1990
Errors found in a common physics experiment to measure acceleration resulting from gravity using a linear air track are investigated. Glider position at release and initial velocity are shown to be sources of systematic error. (CW)
Descriptors: Acceleration (Physics), College Science, Computation, Higher Education
Peer reviewedEsbenshade, Donald H., Jr. – Physics Teacher, 1991
Develops the idea of fractals through a laboratory activity that calculates the fractal dimension of ordinary white bread. Extends use of the fractal dimension to compare other complex structures as other breads and sponges. (MDH)
Descriptors: Computation, Enrichment Activities, Fractals, High Schools
Peer reviewedRogis, Jeanne A. – Science Scope, 1991
Presents a class activity in which students use trigonometry to calculate the height attained by a water rocket. Provides a lesson plan that includes a list of materials needed, procedures to carry out the experiment, suggestions to extend the activity, and a reproducible worksheet for the students to register their calculations. (MDH)
