View Resource Introduction to Topographical Maps

From Foothill College and the Using a Web-Based GIS to Teach Problem-Based Science in High School and College project, this module introduces students to topographic maps. The exercise provides a definition of topographic maps and rules for understanding them. The second half of the exercise asks students general questions on topographic maps and specific questions on the Montara Mountain...

View Resource Coordinates

In this activity, developed by the Lane Community College Geo-STAC program?, students "understand geographic location (absolute and relative) using an interactive Web-based GIS map." The lesson helps review basic concepts of coordinate geometry as they move about the world identifying coordinate relationships and important reference lines. On the site, visitors will find a link to the student a...

View Resource Map-It: Form-based Simple Map Generator

This map generator takes longitude/latitude pairs as input and plots them on a Mercator projection map along with land/sea and political boundaries. The map bounds will be about 10 percent larger than the bounds of the entered data points. As an example, the generator is loaded with default values that yield a map of Cape Cod, Massachusetts, generated by supplying the longitude and latitude...

View Resource MY NASA DATA Contributed Lesson 4: Snow Cover by Latitude

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the data to create graphs comparing the amount (percentage) of snow cover along selected latitudes. Students will make graphs from the data microset, then use the graphs to investigate the percentage of snow cover by latitude. The...

View Resource Dimensions of the Earth

This unit consists of a variety of materials that explain the shape of the Earth and how it is measured. There is a set of 'proofs' that the Earth is round, an account of how Greek geographer and mathematician Eratosthenes deduced that Earth's surface was curved, and explanations of how roundness, latitude, and longitude are measured. There is also information on time zones, contour (isoline)...
