“Boxed Up Circuits” and
Electromagnets Lead to Grid Work

CURENT RET Presentation
July 1, 2014
Knoxville, Tennessee
Program Focus
To incorporate the embedded engineering
standards into 8th grade science and physical
science curriculum in electromagnetism and
electricity.
Students need to understand what engineering is
and how it relates to their lives, to bridge the gap
between math and science, and to help them
strengthen their critical thinking skills.
A big problem I find is that the information is
taught separate and connections are not always
made to promote the big picture.
Program Focus
•The end result from my time at CURENT:
•Electromagnetism Unit Plan-8th grade
•Electromagnetism and Electricity Unit-H Phy Sci
•Focusing on
•Motors and generators
•Magnets and magnetic fields
•Electricity generation
•Renewable and nonrenewable energies
•Wind Turbines
•Hydroelectric generator
•Solar Panels
•Electric circuits
•Incorporation of grid in small scale models
TN State Standards
8th Grade
Embedded standards:
GLE 0807.Inq.2 Use appropriate tools and techniques to gather,
organize, analyze, and
interpret data.
GLE 0807.Inq.3 Synthesize information to determine cause and
effect relationships between
evidence and explanations.
Phsyical Science Standards:
GLE 0807.12.1 Investigate the relationship between magnetism and
electricity.
GLE 0807.12.2 Design an investigation to change the strength of
an electromagnet.
GLE 0807.12.3 Compare and contrast the earth’s magnetic field to
that of a magnet and an electromagnet.
TN State Standards
Physical Science
Embedded standards:
CLE 3202.T/E.3 Explain the relationship between the properties of a
material and the use of the material in the application of a
technology.
CLE 3202.T/E.4 Describe the dynamic interplay among science,
technology, and engineering within living, earth-space, and
physical systems.
Phsyical Science Standards:
CLE 3202.2.1 Investigate the properties and behaviors of
mechanical and electromagnetic waves.
CLE 3202.2.4 Probe the fundamental principles and applications of
electricity.
