This Microsoft Word document works well for guiding student research! It features 6 places students can choose from for researching extreme places located in the US (you can definitely add more or take some off depending upon what you want students to research).
Places to research include: Death Valley, Yellowstone National Park, Redwood National Park, Hawaiian Volcanoes, Denali National Park (Mount McKinley), and the Florida Everglades.
[Other places not listed but would work well for this research project include the Grand Canyon and Mount Saint Helen's]
It guides student thinking and also has a place for them to document website resources!
