Forces and Motion

Energy: Conservation and Transfer

  • NCES.7.P.2 Understand forms of energy, energy transfer and transformation and conservation in mechanical systems.

    • NCES.7.P.2.1 Explain how kinetic and potential energy contribute to the mechanical energy of an object.

    • NCES.7.P.2.2 Explain how energy can be transformed from one form to another (specifically potential energy and kinetic energy) using a model or diagram of a moving object (roller coaster, pendulum, or cars on ramps as examples).

    • NCES.7.P.2.3 Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass.

    • NCES.7.P.2.4 Explain how simple machines such as inclined planes, pulleys, levers and wheel and axles are used to create mechanical advantage and increase efficiency.

Earth Systems, Structures and Processes

  • NCES.7.E.1 Understand how the cycling of matter (water and gases) in and out of the atmosphere relates to Earth's atmosphere, weather and climate and the effects of the atmosphere on humans.
