The Standard

Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.

What This Standard Means

What Students Need to Do

Students build and interpret diagrams, written models, or simulations that track energy through a visible event. They connect organized particle motion to kinetic energy, random particle motion to thermal energy, and position or charge arrangements to field energy.

What Mastery Looks Like

Given a falling ball, warming brake, or charged capacitor, students label the system and show where energy is before and after the change. Their model accounts for the energy and explains each transfer using particle motion or gravitational or electric fields.

Common Misconceptions

Students may treat heat as a substance that objects contain, rather than linking thermal energy to random particle motion. They may place gravitational energy inside a raised object instead of in the interaction between the object and Earth. They may also assume charged plates contain energy separately, rather than modeling energy in the electric field between them.

How to Assess It

Give this exit ticket: "A ball is released from a shelf, hits the floor, and rebounds to half its starting height. Draw a three-panel model showing gravitational field energy and organized and random particle motion. Explain why the rebound is lower."

Ways to Teach It

  1. Have pairs rub a wood block with sandpaper for 30 seconds, measure its surface temperature, and draw particle diagrams before and after.

  2. Students write a claim answering, "Where is the energy of a book on a shelf stored?" and defend a field model involving Earth.

  3. Teams match event cards, such as warm brakes and charged plates, to model cards showing particle motion or field energy.

  4. Analyze a bicycle braking diagram and trace energy from the moving bicycle to random particle motion in the brake pads and wheel rim.
