Lesson 3 : Engineer
Demonstrate their understanding of the relationship between electricity and magnetism by designing an advocacy campaign that educates homeowners about how electricity and magnetism work to avoid the negative impacts of exposure to magnetism from high current power lines.
- 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.]
