In this lesson, students would use the same journals they used for the lesson above. They would mark on the map where the authors found the flora and fauna: P would be for plants and A for animals.
I found the following lesson in Google Earth lessons (http://www.gelessons.com/lessons/). It will work perfectly for my biome unit with a few modifications. I would change the word habitat to biome, and I would not include caves in the list of habitats, but instead substitute tundra, and Arctic.
