Electricity and Magnetism
(Electrostatics, Circuits, Electric Fields, Electromagnetism)
Stage 1 – Desired Results
Established Goals
(Non-negotiables) (Washington State Content Science
Standards)
Students will be able to independently use their learning to …
 Understand how electric power is generated and how energy is transferred by potential difference
in order to do work
 illustrate the electromagnetic spectrum with a labeled diagram, showing how regions of the
spectrum differ regarding wavelength, frequency, and energy, and how they are used (e.g., infrared
in heat lamps, microwaves for heating food, X-rays for medical imagining.)
9-11 PS1G
Electrical force is a force of nature
independent of gravity that exists between charged
objects. Opposite charges attract while like charges repel.
9-11 PS1H
Electricity and magnetism are two
aspects of a single electromagnetic force. Moving electric
charges produce magnetic forces, and moving magnets
produce electric forces.
9-11 PS3E Electromagnetic waves differ from physical
waves because they do not require a medium and they all
travel at the same speed in a vacuum. This is the
maximum speed that any object or wave can travel.
Forms of electromagnetic waves include Xrays,
ultraviolet, visible light, infrared, and radio.

Transfer
Two charged objects will attract or repel
each other, and be able to explain why.
An electric current flowing in a wire will
create a magnetic field around the wire
(electromagnetic effect).
Moving a magnet near a wire will cause an
electric current to flow in the wire (the
generator effect).
Recommended Essential Questions
Students will keep considering …
 What causes static electricity?
 How do magnets work?
 How is electrical energy converted to
mechanical energy in electric motors?
 How is electric energy stored and
transferred?
 What’s the difference between a parallel
and a series circuit? Which one is better?
 What causes the Northern Lights?
