KY.PS. Program of Studies 2006
SC-7-ET. Big Idea: Energy Transformations (Unifying Concepts) - Energy transformations are inherent in almost every system in the universe - from tangible examples at the elementary level, such as heat production in simple Earth and physical systems to more abstract ideas beginning at middle school, such as those transformations involved in the growth, dying and decay of living systems. The use of models to illustrate the often invisible and abstract notions of energy transfer will aid in conceptualization, especially as students move from the macroscopic level of observation and evidence (primarily elementary school) to the microscopic interactions at the atomic level (middle and high school levels). (Academic Expectations 2.1, 2.2, 2.3, 2.4)
SC-7-ET-S-5. Program of Studies: Skills and Concepts - Students will equate work done on an object with change in energy of the object
SC-7-MF. Big Idea: Motion and Forces (Physical Science) - Whether observing airplanes, baseballs, planets, or people, the motion of all bodies is governed by the same basic rules. At the middle level, qualitative descriptions of the relationship between forces and motion will provide the foundation for quantitative applications of Newton's Laws. (Academic Expectations 2.1, 2.2, 2.3)
SC-7-MF-S-5. Program of Studies: Skills and Concepts - Students will calculate work as the product of force and distance moved in the direction of the force
