- discuss at least five different examples of extremophiles on Earth and discuss how they thrive in their special environments (or, each person can choose one extremophile to research and share with the rest of the group). Extrapolate these extreme survival abilities to the kinds of life that might be able to survive in the very different environments throughout our Solar System?
