Possible Student Misconceptions

●Students may not differentiate between variables and controls in an investigation.

●Students may try to change multiple parts of an investigation causing there to be too many
variables.

●Students may not understand that only one variable can change during an experimental
investigation.

●Students may think that magnets act on all metals.

Explain how the distance between the car tester and the car impacted
how the car moved.

The car moved
faster and farther
when the distance
was short
between the car
tester and the car.

What is a noncontact force?

A noncontact force is a force that acts on an object without
touching the object. Gravity and magnetism are noncontact
forces. You can plan and conduct a descriptive investigation to explore the patterns of noncontact forces by using a magnet to pick up objects.

What happens when poles of magnets are close?

Magnets attract,or pull objects closer, when opposite poles are
toward each other. Magnets repel,or push objects away, when
like poles are toward each other.

Force

A push or pull, which
may cause a change in
an object’s motion

Magnetism

The physical
property of being
magnetic
Objects can either
attract to, not attract
to, or repel from a
magnet

Attract

To draw by a
physical force
causing to
approach,
adhere, or unite;
pull (opposed to
repel).

Repel

To force
(something) to
move away or
apart.

20

Poles

The parts of the
magnet with the
strongest
magnetic force

21

Investigate Magnetism

Describe what happens when the two magnets in each row
interact.

22

Patterns of Magnetism

Draw and label another object that is attracted to a magnet.
Draw an arrow to show where the object would move.

DOL: Given
scenarios, SW
correctly describe
patterns of
magnetism in at
least 4 of 5
questions.
