Stage 1 - Identify Desired Results
Narrative about this Unit of Study: (including the Big Idea)
Big Idea: Electric Energy and Magnetic Force Make Our World Go Around
In this unit, students will be able to demonstrate their understanding of the ways in which energy and forces make the world go around.
Students will do this through in-depth inquiry, observation and experimentation with electrical circuits and magnets. They will also research
these topics in order to report information about the processes involved in electricity and magnetism with specific emphasis paid to
explaining procedures, analyzing results of experiments and drawing conclusions. Additionally, students will develop the scientific language
in order to read, write and orally share their experiences in discovering the properties of electricity and magnetism with others.
Learning Outcomes – Identified Primary Standards
What relevant goals will this unit address?
CCLS Science Standards: Science, the Physical Setting
PERFORMANCE INDICATOR 3.1
Observe and describe properties of materials, using appropriate tools.
3.1c Objects have properties that can be observed, described, and/or measured: length, width, volume, size, shape, mass or weight,
temperature, texture, flexibility, reflectiveness of light.

Session 4
 Electricity can flow
because energy can be
transferred
 Electricity travels in a
closed circuit and stops
when the circuit is open
 Electricity interacts with
matter to make things
work, e.g. a light bulb light
Share – Students report questions
raised and new information
learned
Science - Investigation #1
Science journal - diagram
Demo/Discussion – Students
create a circuit by joining all of
their hands except for one
opening between 2 students.
When one person turns on the
“switch,” the circle is closed and
students let the electricity flow
around the circle by squeezing
hands in chain reaction until it
goes all the way around and
reaches the “lightbulb”
Circuit Materials: Wire (conductor),
light bulb, battery
Read Aloud: In Their Own Words:
Thomas Edison by George Sullivan
(chapter showing Edison’s diagrams)
Investigation #1 – Students, in lab
groups, are given circuit materials
and try to make the light bulb
light as an exploration with the
materials
Teach – Concept of circuit, power
source (battery), wire, switch
(open/close)
Session 5
 Some materials conduct
electricity and others do
Journal - Students sketch their
various efforts to make the light
bulb light. They diagram their
working circuit.
Science - Investigation #2
Which is a conductor? Which is
an insulator?
Science journal – chart data
Circuit Materials: Wire (conductor),
light bulb, battery, pencil (insulator),
metal nail (conductor), plastic pen

not
Some materials conduct
electricity better than
other materials
cap (insulator)
Discuss/Review – What did we
use to pass the electricity along
the circuit last time?
Teach – Wire is a conductor
because it passes the electricity
along. Some materials like wire
and the light bulb allow electricity
to flow. These are conductors.
Other materials don’t pass
electricity and these are called
insulators. Today you will make a
circuit and attach some objects to
find out which objects are
conductors and which are
insulators?
Investigation – Students work in
lab groups to test out different
materials to determine which
ones conduct and which insulate.
They record their findings in their
science journals.
Session 6
 Some materials conduct
electricity and others do
not
 Electricity can help, but it
can also harm

e.g. Don’t let wires trail across the
floor, don’t put your finger in a
socket, get parents to change
light bulbs, never touch electrical
things with wet hands, dry
yourself before touching
switches, etc.
