Introduction to Google Earth
Grade: 6-12 Group Size: 1 – 40 (based on computer availability/sharing) Time: 30 min BACKGROUND

Google Earth “combines the power of Google Search with satellite imagery, maps, terrain and 3D
buildings to put the world's geographic information at your fingertips.” “Google Earth maps the earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. The viewer shows houses, the color of cars, and even the shadows of people and street signs. The degree of resolution available is based somewhat on the points of interest, but most land (except for some islands) is covered in at least 15 meters of resolution. Las Vegas, Nevada and Cambridge, Massachusetts include examples of the highest resolution, at 15 cm (6 inches). “ Google Earth allows users to • search for addresses (schools, parks, islands, research locations) • enter coordinates (of specific locations, satellite tagged animals, GPS, etc.) • tilt and rotate the view to see 3D terrain and buildings • or use the mouse to browse to any place in the world for a close up view Google Earth also has digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission. This means one can view the Grand Canyon or Mount Everest in three dimensions, instead of 2D like other map programs/sites. In addition, Google has provided a layer allowing one to see 3D buildings for many major cities in the US and Japan. This software is available under three different licenses. Google Earth, the free version is the one you will be using. There are also two upgrades that may be purchased Google Earth Plus which includes additional features, and Google Earth Professional which is intended for commercial use. OVERVIEW Students will learn how to download, install, and perform basic operation with Google Earth. This lesson is an introduction to how to load and operate Google Earth. This GIS software is FREE and can be easily understood. This lesson requires no additional background data and is intended to serve as a starter lesson before utilizing the Google Earth software required in other lessons in the workshop. CONTENT STANDARDS PERFORMANCE OBJECTIVES Students will learn how to download and install the free version of Google Earth. Students will perform basic operations in Google Earth and become comfortable with the basic tools it offers. MATERIALS Computers should be • Windows XP or Vista and Pentium 4 (see stickers on front of computer) • Mac OS X version 10.4 and G4 • Windows 2000 Pentium 3 and Mac G3 may also be tried, but will tend to experience problems

Internet connection should be High Speed internet is needed, at least a DSL connection. The faster the connection the better the experience. ☺ Students may work in pairs, depending on availability of computers at your location. The more computers being used for this program, the slower your connection will get. This lesson may also be demonstrated allowing the students to rotate through the computers afterward as a station. Worksheets Print Activity 1 and Activity 2 for each student. ADVANCE PREPARATION You need to download Google Earth (free version) software on your own computer and try this lesson and at least one additional lesson on mapping from the list of activities prior to using this lesson with your students. It is advisable to load Google Earth on all computers PRIOR to class. This is a large file and could be downloaded once then transferred to other computers using a thumb drive or other method. Please check with your school’s Technology Coordinator if you need help. There are two pages (can be run back to back) that need to be printed for each student for this Activity 1 and Activity 2

PROCEDURE 1. How to download Google Earth software: a. Go to http://earth.google.com/download-earth.html b. This process will take a period of time, at least several minutes, as it is a large file. c. If Google Earth is already loaded (as recommended) on student computers you may demonstrate this. 2. Activity 1 a. Have students open Google Earth and complete the sheet for Activity 1 b. for teacher answers http://earth.google.com/userguide/v4/index.html#navigating 3. Activity 2 a. directions are clear for additional help refer students to Help in Google Earth b. Help Tutorials

EXTENSIONS Have trained students work as helpers. Have students discover additional features in the tutorials section. Have students complete one of the other lessons on the site.
