Dimensions of a Planet.
Hayward, O. T.; And Others
This publication is one of a series of single-topic problem modules designed for use in undergraduate geology and earth science courses. The first section, "Ain't It Flat? A Series of Experiments in Geodesy," presents various experiments for determining the earth's circumference (historically) and describes the use of satellites in determining the precise shape of the earth. The second section, "Put it on the Scales," describes the Cavendish experiment to determine the value of the universal gravitational constant, G, and to use this value in calculating the mass of the earth. The values for the size and mass of the earth are utilized in the final chapter to determine the mean density of the earth. The modules in this series are self-contained, inquiry and problem solving oriented, and designed to be open-ended. (PR)
