35. GPS STANDARDS/ELEMENTS SPS8 Students will determine relationships among force, mass, and motion. e. Calculate amounts of work and mechanical advantage using simple machines prerequisite skills: identifying simple machines ELA9W1f. Uses traditional structures for conveying information (i.e., chronological order, cause and effect, similarity and difference, posing and answering a question) Can be used with a unit on Henry Ford to include the following standard SSUSH16 The student will identify key developments in the aftermath of WWI b. Identify Henry Ford, mass production and the automobile The Automobile: Machines Make Work Easier Graphic Organizers Created by Juanita Pritchard, Cobb County Public Schools Directions: For use after reading/viewing the PowerPoint: The Automobile: Machines Make Work Easier Use the simple graphic organizer (4 locations) with the first page of 6 graphics for students to indicate simple machines found in automobiles. Use the more complex graphic organizer (6 locations) with graphics to show increased complexity. Use second page of graphics with the first page so that not all the answers are correct – students must identify only the correct items, again showing increased complexity.
