3:PS2-3 Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other.
[Clarification Statement: Examples of an electric force could include the force on hair from an electrically charged balloon and the electrical forces between
a charged rod and pieces of paper; examples of a magnetic force could include the force between two permanent magnets, the force between an
electromagnet and steel paperclips, and the force exerted by one magnet versus the force exerted by two magnets. Examples of cause and effect relationships
could include how the distance between objects affects strength of the force and how the orientation of magnets affects the direction of the magnetic force.]
[Assessment Boundary: Assessment is limited to forces produced by objects that can be manipulated by students, and electrical interactions are limited to
static electricity.]
Essential Questions
Define Electricity and
Magnetism, along with
how they interact with
objects
Content Statements
Enduring Understandings
Magnets have two poles and opposites
attract.
The distance of an object from a magnet
or a statically charged object has it affect
on it intensity.
Common Core Standards
Connections
There are invisible forces that act
on objects
ELA / Literacy - RI.3.1 RI.3.3 RI.3.8
W.3.7 W.3.8 SL.3.3
There is a connection between
electricity and magnetism
Mathematics - MP.2 MP.5 3.MD.A.2
What happens to an path when
no other force is added to the
object.
What happens when you have
equal forces on an object, like a
seesaw?
Magnets can repel or attract
other magnets, but they attract all
matter made of iron. Magnets
can make some things move
without being touched.
Labs, Investigation, and Student Experiences
Investigation: Have two magnets and have students try to get the magnets to
stick together. Have students charge a balloon with static electricity and show
the interactions on hair.
Suggested Modifications (ELLs, Special Education, Gifted and

Desired Results
SWBAT: Explain how two magnets react when placed near each other,
including the properties of magnets.
Sample Assessments
The movement of electric charges is?\
1. sound energy
2. open circuit
3. light energy
4. electric energy
What are the two poles on a magnet?
1. north and north
2. south and north
3. west and south
4. south and south
If you place a south pole of a magnet close to the south pole of another
magnet, they will attract each other.
1. True
2. False
