Grade Level/Subject Physics - static electricity
Stage 1: Desired Results
Enduring Understanding
Charged particles will attract or repel each other, depending on the sign of the charges involved, with a force directly related to the size of the charge and inversely proportional to the square of the distance between them.

Essential Questions
• What's the best way to shock someone? • What's the best way to avoid being shocked?
Knowledge and Skills
Students should know:
• How to compare and contrast electrical conductors with electrical insulators. • What electric fields are and why they are useful. • How to compare and contrast Coulomb's with Newton's Law of Universal Gravitation?
Students should be able to:
• Explain the behavior of various electrical phenomena based on the principles of static electricity. • Calculate the force between two or more changed objects; • Calculate the force exerted on a charged object in an electric field; • Draw the electric field in and around various charged objects;
