PS3 help students formulate an answer to the question , “ How can energy be transferred from one object or system to another ?”
At the middle school level, the PS3 Disciplinary Core Idea is broken down into four sub-core ideas: Definitions of Energy, the Conservation of Energy and Energy Transfer, the Relationship between Energy and Forces, and Energy in Chemical Process and Everyday Life. Students develop their understanding of important quali tative ideas about energy including that the interactions of objects can be explained and predicted using the concept of transfer of energy from one object or system of objects to another , and the total change of energy in any system is always equal to the total energy transferred into or out of the system. Students understand that object s that are moving have kinetic energy and that objects may also contain stored (potential) energy, depending on their relative positions. Students will also come to know the difference between energy and temperature , and begin to develop an understanding of the relationship between force and energy. Students are also able to apply an understanding of design to the process of energy transfer.
The performance expectations in PS3 expect students to demonstrate proficiency in developing and using models, planning investigations, analyzing and interpreting data, and designing solutions, and engaging in argument from evidence ; and to use these practices to demonstrate understanding of the core ideas in PS3 .
