← MS-PS2-2
MS-PS2-4 →

Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

Clarification statement: Examples of devices that use electric and magnetic forces could include electromagnets, electric motors, or generators. Examples of data could include the effect of the number of turns of wire on the strength of an electromagnet, or the effect of increasing the number or strength of magnets on the speed of an electric motor.

Assessment boundary: Assessment about questions that require quantitative answers is limited to proportional reasoning and algebraic thinking.

NGSS Dimensions

Performance expectation MS-PS2-3 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices
  • Planning and Carrying Out Investigations
    • Plan an investigation to determine the factors that affect the strength of electric and magnetic forces.
Disciplinary Core Ideas
  • PS2.B: Types of Interactions
    • Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects.
Crosscutting Concepts
  • Cause and Effect
    • Cause and effect relationships may be used to predict phenomena in natural or designed systems.
