Google Lit Trips
Google Lit Trips uses the technologies of Google Earth, Social Networking, and a website together to bring literature to life through virtual mapping. By placing markers on Google Earth tracking the journeys of characters from literature and populating those place markers with a wide variety of supplemental resources, students can “ride along as virtual passengers” on the same journey the characters are taking. Google Lit Trips provides professional development by allowing teacher access to previously constructed Google Lit Trips, and also provides teachers with the ability to interact and post new trips online.
