It's gravity
http://www.sciencenetlinks.com/lessons.cfm?DocID=390
A lesson plan for grades 9–12 Science
In this lesson, students develop students’ understanding of gravity and its critical role as the main mover of the universe. This activity will help students develop ideas about the enormous impact that gravity has on the universe—the shape and movement of the planets, the solar system, stars, and galaxies. After an initial discussion to assess prior knowledge about gravity, students complete further research using web resources from the Adler Planetarium. Then, students evaluate popular myths and misconceptions about gravity and consider possible correct answers. Finally, students use the web resources to complete more research and participate in a discussion about modern concepts associated with gravity. Students write a brief essay to conclude the lesson. Science NetLinks provides student handouts, teacher resources, links to helpful websites, and detailed instructions for completing the lesson. This lesson also includes links to similar lessons and other sections from the Adler Planetarium.
