Concept F: Energy can change from one form to
another within and between systems, but the total
amount remains the same
Explain how energy can be transferred (absorbed or
released) or transformed between and within systems
as the total amount of energy remains constant (ie.
Law of Conservation of Energy)
Using a computer program,
students will observe the
transformation of the
gravitational potential energy
and kinetic energy of a
swinging pendulum.
Using additional scenarios,
students will analyze and
justify that energy will be
conserved within a system.
Strand 2: Properties and Principles of Force and Motion
2. Forces affect motion
Major Objectives IS Suggested Activities Suggested Assessments
Concept B: Magnetic forces are related to
electrical forces as different aspects of a single
electromagnetic force.
Recognize changing magnetic fields can produce
electrical current and electric currents can produce
magnetic forces
Concept C: Magnetic forces are related to
electrical forces as different aspects of a single
electromagnetic force.
Predict the effects of an electromagnetic force on the
motion of objects (attract or repel)
Students will construct an
electromagnet from a battery,
wire, and large nail.
Students will note the positive
and negative poles of a magnet
by observing the motion of iron
filings sprinkled onto an
overhead held directly above
the magnet.
Students will create a graph
relating the number of coils in
the wire (and thus its strength)
to the number of paperclips the
magnet can pick up.
Students will test several pure
substances for magnetic
properties, and then use that
information to help identify the
substance.
