High School Physical Science
Standards Addressed
S8P2 Students will be familiar with the forms and transformations of energy.
S8P5. Students will recognize characteristics of gravity, electricity, and magnetism as major kinds of
forces acting in nature.
b. Demonstrate the advantages and disadvantages of series and parallel circuits and how they transfer
energy.
c. Investigate and explain that electric currents and magnets can exert force on each other.
SPS10. Students will investigate the properties of electricity and magnetism.
b. Explain the flow of electrons in terms of
• alternating and direct current
• the relationship among voltage, resistance and current
• simple series and parallel circuits.
c. Investigate applications of magnetism and/or its relationship to the movement of electrical charge as
it relates to
• electromagnets
• simple motors
• permanent magnets
What is the problem?
You have decided to be eco-conscious and
build your own “Tiny House”. You have
completed the first phase of the
construction, you now are ready to “wire”
your house. In order to move into your
new house, you must pass Cobb County’s
electrical inspection by assigned deadline.
How is the solution to be presented?
Using your model of your Tiny House, you must
successfully complete the following tasks in order to pass
your electrical inspection:




A minimum of 4 interior rooms , a front porch light and patio lights must be wired with working lights
Lights in each room/area must operate on a working switch
At least one parallel and one series circuit must be used
You must use a single power source
 You will be required to present the inspector with a very basic electrical schematic which should:
 The proper circuit using the proper symbols
 Labeling the resistance of each load/circuit
 Labeling the voltage
 Calculating the current (amperage) draw on the breaker
 Statement of the breaker rating required for your tiny house (For safety reasons, it must be at least
twice the amperage draw for your loads.)
He may give you bonus points if you can make a working door bell !
