Google Earth can be used in the classroom to create virtual tours for students. Teachers can record tours using the movie camera icon to create placeholders for students to explore. Tours can then be uploaded to the school's learning management system. Some potential activities using virtual tours include creative writing assignments based on literary locations, assessing transport options between points on a tour, developing communication systems based on terrain, and measuring environmental changes over time by using the time slider tool. Additional plug-ins are also available to enhance tours, such as adding natural sounds or exploring underwater terrain.
