KY.CC. Core Content for Assessment v.4.1
SC-07-1.2. Motion and Forces: At the middle level, qualitative descriptions of the relationship between forces and motion will provide the foundation for quantitative applications of Newton's Laws.
SC-07-1.2.1. Physical Science: Students will explain the cause and effect relationship between simple observable motion and unbalanced forces.
SC-07-4.6. Energy Transformations: 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).
SC-07-4.6.3. Students will describe and explain the effects of balanced and unbalanced forces on motion as found in real-life phenomena.
KY.PS. Program of Studies 2006
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-1. Program of Studies: Skills and Concepts - Students will use appropriate tools and technology (e.g., timer, meter stick, balance, spring scale) to investigate the position, speed and motion of objects
SC-7-MF-S-2. Program of Studies: Skills and Concepts - Students will test the cause and effect relationship between straight-line motion and unbalanced forces
SC-7-MF-S-3. Program of Studies: Skills and Concepts - Students will investigate balanced and unbalanced forces and their effect on objects and their motion
SC-7-MF-S-4. Program of Studies: Skills and Concepts - Students will make inferences and draw conclusions about the motion of objects, and predict changes in position and motion as related to the mass or force
SC-7-MF-S-7. Program of Studies: Skills and Concepts - Students will investigate the properties of gravity and observe its effects on objects
SC-7-MF-U-1. Program of Studies: Understandings - Students will understand that an object remains at rest or maintains a constant speed and direction of motion unless an unbalanced force acts on it (inertia).
SC-7-MF-U-2. Program of Studies: Understandings - Students will understand that forces acting against each other can be balanced, canceling each other out and having no net effect.
