Title: Study: Earth Will Be Uninhabitable in 1.75 Billion Years Date: 19 Sep. 2013 Grade: 3 - 6 Subject: Science URL: http://www.newsy.com/videos/study-earth-will-be-uninhabitable-in-1-75-billion-years/ Teacher Information: This Newsy.com video can serve as the starting point to discussions on the habitable zones of stars, the search for lifesustaining planets, and the life cycles of stars and planets. Study: Earth Will Be Uninhabitable in 1.75 Billion Years September 19, 2013 This lesson can be completed in one 50 minute class period. Time periods are given as approximations, however, care should be given to allow for the full time to be allotted for the class discussion. by Jasmine Bailey Phase Preparation Watch Re-watch and answer Group Work Discussion Task(s) Time Write on the board before students enter the room: “What conditions are necessary to sustain life on earth?” Brainstorm to review the following term: “Habitable Zone.” As a class watch the Newsy.com video Study: Earth Will Be Uninhabitable in 1.75 Billion Years at http://www.newsy.com/videos/study-earth-will-be-uninhabitable-in-175-billion-years/ Re-watch the video in pairs and answer the questions on the worksheet at the end o this lesson plan. Form into small groups of four of five and discuss the following questions: What are the necessary conditions for a planet to support life as we know it? Are any of these factors more important than the others? Are there any other planets in our solar system other than Earth that are in the habitable zone? Which one(s)? Do you believe that there is life on planets other than Earth, or is this notion really nothing more than science fiction? Why or why not? Do you think that humanity will ever be able to find and populate another inhabitable world before Earth becomes uninhabitable? Why or why not? Other than because of the Sun’s expansion, what are some other reasons why Earth might become uninhabitable? Full class discussion on the topic and share ideas with the rest of the class.

What are their parents’ opinions on the topic? Students can then share their parents’ views with the class. Students can research scientists’ recent discoveries of potentially habitable worlds outside the solar system. Students can research the life cycle of stars and how that relates to the habitability of planets. Students can choose one of the two research topics listed above and report their findings to the class. varies varies varies varies Looking for related resources?
