Wang, Si; Huang, Shiqi; Liu, Chenchen; Tang, Ziqian; Shi, Qingfan; Schulte, Jurgen – Physics Teacher, 2021
The directional feature of Earth's geomagnetic field has been contributing to the technological development and prosperity of humankind since the invention of the magnetic compass navigation centuries ago. Today, for instance, magnetoresistance sensors are commonly used in nanosatellites and unmanned aerial vehicles for high accuracy geomagnetic…

Kodama, K. – Physics Education, 2009
We describe a simple experiment demonstrating the variation in magnitude of a magnetic field with distance. The method described requires only an ordinary magnetic compass and a permanent magnet. The proposed graphical analysis illustrates a unique method for deducing a general rule of magnetostatics. (Contains 1 table and 6 figures.)

Dutch, Steven I. – Journal of Geological Education, 1986
Describes models which (1) illustrate spreading that varies in rate from place to place; (2) clearly show transform faults as arcs of small circles; and (3) illustrate what happens near a pole of rotation. The models are easy to construct and have been well received by students. (JN)

Mayer, Larry – Journal of Geological Education, 1987
Described is the use of a microcomputer and computer software to simulate the use of geological equipment. The technique uses pictures of the control panel (with switches and dials that can be activated) and a story board that can provide the simulation. A simple seismograph is used as an example of possible simulations. (RH)

Hatcher, Robert D., Jr. – Journal of Geological Education, 1983
Describes a graduate-level tectonics course which includes the historical basis for modern tectonics concepts and an in-depth review of pros/cons of plate tectonics. Tectonic features discussed include: ocean basins; volcanic arcs; continental margins; continents; orogenic belts; foreland fold and thrust belts; volcanic/plutonic belts of orogens;…

Levi, F. A. – Physics Teacher, 1988
Describes a demonstration of Coriolis acceleration. Discusses two different meanings of "Coriolis" and two causes of Coriolis acceleration. Gives a set-up method of the demonstration apparatus by using a rotary disk with rubber tubing for tap water, switches, lamps, battery, and counterweight. Provides two pictures with operating method.…
