attract
to pull objects toward one another
A magnetic force can...
attract or repel an object at a distance.
A magnetic field line represents...
A magnetic field line represents the strength and direction of a magnetic field.
what do you put in the top of the evidence gradient
strong evidence
repel
to push objects away from each other
model
an object, diagram, or computer program that helps us understand something by making it simpler or easier to see
magnetic field
the space around a magnet in which magnetic forces
can act on objects
what do you put in the bottom of the evidence gradient
weaker evidence
magnetic pole
one of the two opposite ends of a magnet
system
a set of interacting parts forming a complex whole
magnetic field line
a line that connects opposite magnetic poles and represents the strength and direction of the magnetic field
What does system do
Each system is a group of parts that interact in a particular way.
variable
something that can be changed and may be measured
repelling force between like poles and an attracting force between opposite poles.
The pattern of magnetic field lines around attracting magnets is
different from the pattern of magnetic field lines around repelling magnets.
what will you do in the SIM
build and test two magnet systems
isolate
to separate or set apart
for the test what should you use to study?
critical juncture
This is the Evidence Gradient. We’ll use it to compare and evaluate pieces of evidence.
in the sim... what will the two magnet systems do
one that will attract and one that will repel.
