Forces and Motion

  • NCES.7.P.1 Understand motion, the effects of forces on motion and the graphical representations of 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.

    • NCES.7.E.1.1 Compare the composition, properties and structure of Earth's atmosphere to include: mixtures of gases and differences in temperature and pressure within layers.

    • NCES.7.E.1.2 Explain how the cycling of water in and out of the atmosphere and atmospheric conditions relate to the weather patterns on Earth.

    • NCES.7.E.1.3 Explain the relationship between the movement of air masses, high and low pressure systems, and frontal boundaries to storms (including thunderstorms, hurricanes, and tornadoes) and other weather conditions that may result.

    • NCES.7.E.1.4 Predict weather conditions and patterns based on information obtained from:

      • Weather data collected from direct observations and measurement (wind speed and direction, air temperature, humidity and air pressure)

      • Weather maps, satellites and radar

      • Cloud shapes and types and associated elevation

    • NCES.7.E.1.5 Explain the influence of convection, global winds and the jet stream on weather and climatic conditions.

    • NCES.7.E.1.6 Conclude that the good health of humans requires: monitoring the atmosphere, maintaining air quality and stewardship.

Structures and Functions of Living Organisms

  • NCES.7.L.1 Understand the processes, structures and functions of living organisms that enable them to survive, reproduce and carry out the basic functions of life.

Evolution and Genetics
