Exploring Magnetism on Earth

Understanding the power of magnetism on Earth isn�t always easy, and students and teachers alike will be glad to find out about this handy guide to the subject. Created by experts at NASA, this 15-page teacher�s guide was designed in partnership with other educators at Berkeley and several other participating institutions. The guide contains problems which examine Earth�s changing magnetic field in time and space, and how these changes can impact navigation on Earth�s surface. In terms of specific activities, the guide includes exercises on navigating the earth with a compass, the declining magnetic field, and the reversal of magnetic polarity. Each of these activities is explained in detail, and they all include relevant illustrations, graphs, questions, and an answer key.
