Magnetism in Our Lives
Today’s Agenda
► Opener:
Where is the magnetic field of a bar
magnet the strongest?
► Watch the Modern Marvels: Magnets Video
(complete the handout)
► Go over the handout in small groups and as a
class.
► Honors: Build an electromagnet. See its affect on
compasses, and try to pick up paperclips.
► Closure: Does an electromagnet have poles? How
do you know?
Curriculum
► Big
Idea: Energy can be transferred between
objects and/or can be converted into different
forms.
► Concept: Electricity is the result of converting one
form of energy into another and the flow of
electrons via a conductor.
► PA Standard 3.2.P.B4: Explain how stationary and
moving particles result in electricity and
magnetism. Develop qualitative and quantitative
understanding of current, voltage, resistance, and
the connections among them. Explain how
electrical induction is applied in technology.

Big Idea: Energy can be transferred between objects and/or
can be converted into different forms.
Concept #1: Energy can take many different forms including
mechanical, thermal, chemical, and electromagnetic.
Concept #2: Energy can be transferred thermally, mechanically,
electrically or chemically in a system.
Concept #3: Energy is conserved (Law of conservation of energy).
Competency: Describe sources and forms of energy and explain their
transformations.
PA Standard 3.2.10.B2: Explain how the overall energy flowing through a
system remains constant.

Idea: Energy can be transferred
between objects and/or can be
converted into different forms.
► Concept: Electricity is the result of
converting one form of energy into another
and the flow of electrons via a conductor.
PA Standard:3.2.12.B2: Explain how energy
flowing through an open system can be
lost.
Curriculum
Big Idea (from PDE): All motion can be explained using
the laws of the conservation of energy, the
conservation of momentum, and/or the
conservation of angular momentum.
Goal (from HHS):
► Calculate Power
PA Standard:
3.2.10.B2: Explain how the overall energy flowing
through a system remains constant. Describe the
work-energy theorem.
Explain the relationships between work and power.
