Graphic OrganizersCreated 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.
