Unit 5: Electricity and Magnetism

STANDARD: S8P5   Obtain, evaluate, and communicate information about gravity, electricity, and magnetism as major forces acting in nature.

ELEMENT: S8P5.c   Plan and carry out investigations to identify the factors (e.g., distance between objects, magnetic force produced by an electromagnet with varying number of wire turns, varying number or size of dry cells, and varying size of iron core) that affect the strength of electric and magnetic forces.
