This teaching guide is designed to introduce the concepts of seismic waves that propagate within the Earth, and to provide ideas and suggestions for how to teach about seismic waves. The guide provides information on the types and properties of seismic waves and instructions for using the slinky to effectively demonstrate seismic wave characteristics and wave propagation. Most of the activities described in the guide are useful both as demonstrations for the teacher and as exploratory activities for students.
In this activity, students will develop and be able to manipulate a grid coordinate system on a 7.5 minute series local topographic map. Students will learn to use the grid coordinate protractor (GCP) to plot azimuth values as a means of indicating direction on these maps; they will also learn to perform simple map traverses.
