SPECIFIC BIOMES
Don't forget that there are many specific biomes that you might want to explore virtually with your students. In fact, it might be fun to explore a specific biome such as the Everglades, then as a class, use that exploration to create a definition of that biome. Do further research on that biome to see how your class's definition holds up under scrutiny. We've included the International Space Station, too! Challenge your students to figure out why.
