4.P.1 Explain how various forces affect the motion of an object.
4.P.1.1 Explain how magnets interact with all things made of iron and with other magnets to
produce motion without touching them.
4.P.1.2 Explain how electrically charged objects push or pull on other electrically charged
objects and produce motion.
4.P.2 Understand the composition and properties of matter before and after they undergo a
change or interaction.
4.P.2.1 Compare the physical properties of samples of matter: strength, hardness, flexibility,
ability to conduct heat, ability to conduct electricity, ability to be attracted by magnets, reactions
to water and fire.*
4.P.3 Recognize that energy takes various forms that may be grouped based on their
interaction with matter.
4.P.3.1 Recognize the basic forms of energy (light, sound, heat, electrical, and magnetic) as the
ability to cause motion or create change.
4.P.3.2 Recognize that light travels in a straight line until it strikes an object or travels from one
medium to another, and that light can be reflected, refracted, and absorbed.
*In this unit, the emphasis is on conductors, nonconductors (insulators), and the ability to be
attracted by magnets.
Essential Question for Unit
How do electricity and magnetism work, and how can they work together?
Unit Pre-Assessment
Two formative assessment probes are available for this unit. “Magnets in Water” can be found
on page 67 of Uncovering Student Ideas in Science, 25 Formative Assessment Probes Volume 4
(Green Cover), by Page Keeley et al. This probe elicits students’ ideas about magnetism,
specifically if students think air is required for magnets to work. Another probe called “Batteries,
Bulbs, and Wires” is available on page 57 of Uncovering Student Ideas in Science Volume 3
(Green Cover), by Page Keeley et al. This probe reveals whether students recognize the pathway
of electricity in a complete circuit. “Magnets in Water” can be administered at the beginning of
the unit because Investigation 1 is an exploration of magnets and magnetism. “Batteries, Bulbs,
and Wires” can be administered at the beginning of Lesson 5 (Investigation 2, part 1- Lighting a
Bulb).
Preparing for the Unit
 Make sure the D-cells and bulbs in the kit are fresh; may need to replace mid-unit
 Make copies of assessment charts in teacher guide

Lesson 1 - Investigation 1, Part 1: Investigating Magnets and Materials
Students find objects that contain iron stick to permanent magnets while other objects do not.
They discover that two magnets will either attract or repel one another, depending on the
orientation of their poles. The agent responsible for this behavior is the magnetic force.

produce motion without touching them.
4.P.2.1 Compare physical properties of samples of matter: (strength, hardness, flexibility, ability

water and fire.)

Activity

Following the formative assessment
probe, engage students in a game called
“Describe the Object.” Place an object
in a bag and invite a student to reach in
the bag to describe the characteristics
(size, shape, feel, etc) of the object
while the rest of the class is challenged
to draw what they think the object
looks like.
Ask students to describe other magnets
they have seen or played with.
Invite students to experiment with
magnets at their seats, around the
classroom, and in groups. (Discuss
areas that students should avoid such

calculators, or computers as the
magnets can "erase" the information.)
Lead a discussion so students share the
results of things-that-stick.
Introduce the bag of test objects.
