Electricity and Magnetism
Objectives: Students will be able to:
►design and conduct inquiry experiments
to create and study the effects of an electrostatic force on the motion
of an object.
►
describe with a diagram the flow of electrical charges caused by static
electricity
►describe the characteristics of static
electricity and how it is formed

►
communicate scientific vocabulary properly when
explaining the paths of electricity with words such as static electricity,
discharge, conductor, insulator, repel, attract, positive and negative
charges
►
describe how lightning is formed and where
lightning goes
►
evaluate safety situations when lightning
threatens

Electricity and Magnetism
Objectives
The student will be able
to:
►explore and
explain what is needed to make a flashlight bulb work.
►infer that a complete
path must be created to make a bulb work.
►examine and operationally define
closed and open circuits.
►explain and compare
electrical current: alternating current (AC) and direct
current (DC)
►construct,
compare and contrast
between a series and parallel circuit.

flows though a parallel circuit than a series circuit.
►represent and read about electrical
circuits using schematic drawings.
►understand the relationship
between current available and the results within a circuit

For the teacher to use:
Electricity and Tennis Balls This is a way to
understand the concept of DC electricity current using tennis balls as a model.
The Electricity Book 1: Looking at Simple Circuits
We can use this on the SmartBoard to demonstrate how the light
bulb works, how the electricity flows through the light bulb, and how the
circuit is formed, plus there is a quiz at the end. Use at home for a
review!
The Electricity Book 2: What Is Electricity? We can use
this on the SmartBoard to demonstrate just what electricity is and how it
"flows" similar to how a river flows. Use it to review at home.
 Conductors and Insulators Excellent site to learn about the two
through interactive activities.Conductors

Edison's Miracle
of Light Best clicks are the time line of Edison's life, photo gallery
of eight of his inventions, and the Special Features. "In 1887 direct current
(DC) was king. At that time there were 121 Edison power stations scattered
across the United States delivering DC electricity to its customers." Learn all
about AC/DC in the first interactive Special Feature. The second is a collection
of five fun tunes the Edison company produced on phonograph records between 1919
and 1926.

Essential Question: How can you make electricity?
Books
The student will be able to:
►Become familiar with magnetic safety and know that magnets should never be
near electronic equipment, speakers, software, floppy disks, CD’s. audio
or video tapes, wind up watches, credit cards, Zip cards, telephones,
answering machines, TV’s, computers, monitors, etc.
►determine
whether or not an object or material can be attracted to a magnet.
►explain the concept of magnetic domains—what they
are and how they can be destroyed.
►describe the concepts of attraction and repelling.
►explain and sketch the
concept of a magnetic force field.
►describe the
relationship between electricity and magnetism.
►construct an electromagnet and
determine what makes an electromagnet stronger.
►design a simple system that can defy gravity.
►construct a
simple motor and explain how it transforms energy into mechanical energy.
►compare naturally
occurring magnets to electromagnets.
