What are Simple Machines?
This concept comparison frame contrasts the 6 basic simple machines; the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. Several of these simple machines are related to each other. But, each has a specific purpose in the world of doing work, which is related to efficiency and mechanical advantage.
The Concept Comparison Routine is used help compare and contrast key concepts. Specifically, students use like and unlike characteristics and categories shared and not shared by two or more concepts to better understand the overall concept. Students taught using the Content Enhancement routines earned higher total test scores than did students taught using the lecture-discussion method.
Personally, I use the Content Enhancement Routines to figure out what I want to say and how I want to say it. It keeps my "Sage on the Stage" time limited to what fits onto the page (about 45 minutes of directed class discussion).
This product includes both the completed concept comparison, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in. It includes warm ups, worksheets, and recommended videos for review, and it's is in Microsoft Word .doc form so that Ts can customize the discussion to fit the needs of their Ss.
This Content Enhancement Routine is classroom tested to help students with the following Florida Next Generation Sunshine State Standards in Science:
SC.912.P.10.1 Differentiate among the various forms of energy and recognize that they can be transformed from one form to others.
SC.912.P.10.2 Explore the Law of Conservation of Energy by differentiating among open, closed, and isolated systems and explain that the total energy in an isolated system is a conserved quantity.
SC.912.P.10.3 Compare and contrast work and power qualitatively and quantitatively.
