UNIT PLAN
Subject: Physical Science
Unit #_7_
Unit Name_Electricity and Magnetism _
Big Idea/Theme:
The flow of electric charges in a circuit is a source of electrical energy and can induce
magnetism, and vice versa.
Culminating Assessment:
 Students will apply their knowledge of scientific inquiry, magnets, coils, and
currents to design and complete laboratory activities investigating electromagnetic
induction by building a simple generator.
 Students will apply their knowledge of scientific inquiry, electricity, and circuits
to design and construct simple series and parallel circuits during a laboratory
activity.
 On a written assessment, students will be able to solve problems involving Ohm’s
law, diagram and label series and parallel circuits, and using a diagram of a
generator identify, label, and sequence the steps of the production of the electric
current used to charge their cell phone (real world).
