Earth Bits - Global Warming
For Earth Day 2006, lessons on global warming were developed by Google and publisher Scholastic. They built a site that "lets students literally fly across the world and see for themselves how the earth is changing" using satellite imagery. It is designed for 6th to 8th grade students, and can be found at "Explore Your Earth". Educators need to download Google Earth in order to use the lesson plans but the basic version of the virtual globe is free.
