NGSS HS-PS3-5
The Standard
Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.

What This Standard Means
What Students Need to Do
- Students create diagrams for two charged or magnetic objects. They show force direction and explain how changing distance affects motion and energy stored in the interaction field.
What Mastery Looks Like
- A correct model shows equal and opposite forces and predicts attraction or repulsion. Students connect changes in distance and motion to changes in kinetic energy and energy stored in the field.
Common Misconceptions
- Students may draw a force on only one object or assume a field acts in only one direction. They may think faster motion creates energy, or that moving objects closer always lowers potential energy, even for repelling pairs.
How to Assess It
- Exit ticket: Draw two like charges released from rest. Add force arrows, predict their motion, and state how kinetic energy and field energy change as separation grows.

Ways to Teach It
Place two ring magnets on low-friction carts, release them, then have students sketch motion, force arrows, and energy bar charts.
Prompt: Two opposite charges move closer. Explain what happens to force, electric potential energy, field energy, and kinetic energy.
Run a card sort matching charge or magnet arrangements with attraction, repulsion, force arrows, and higher or lower potential energy.
Analyze a magnetic cabinet latch as the door closes, predicting force direction, motion, and how energy shifts between motion and field.
