The activities in this investigation train students to differentiate between physical (natural) and human-made features. Using both space shuttle photographs and satellite images, students will identify some of Earth's prominent natural and human-made features. Students begin by matching images of individual physical features with their definitions, which they then must locate on larger scale images. Photos of three U.S. cities allow students to practice identifying both types of features. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. The teacher's guide will begin with a two-page module overview and list of all standards addressed. This is Investigation 1 of four found in the Grades K-4 Module 3 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the four investigations in Module 3, while related, can be done independently.
