Love Earth is an organization located in the UK and part of the BBC. Their work is geared toward educating the public about the earth’s systems and its inhabitants. Loaded with beautiful still photos, videos, and blogs, this site is a powerful resource for any grade level science teacher.
One of the cool things I found here is tracking animals and their migratory patterns. Love Earth presents their data via Google Earth. Key points in the pattern from the weekly updates have blog entries and other media to extend the experience for the user. Take my advice, science teachers. Check this site out. The kids will absolutely love the experience it provides.
