Graphing, Gravity, and Magnetism Review
The Graphing Blueprint
X-Axis: Independent
The factor I change in the experiment. Think: "The Cause."
Y-Axis: Dependent
The data we measure. Think: "The Effect."
Dependent (Y)
Independent (X)
GRAPH AREA
Variable Challenge
"A student measures how the distance from a magnet affects how many paperclips it can pick up."
Independent (X) Distance
Dependent (Y) Paperclips
Remember: The Dependent variable depends on the Independent variable!
Gravity: The Downward Pull
Always Toward Center
Gravity pulls everything toward the center of the Earth.
Mass = Pull
More mass means a stronger pull. That's why Earth pulls us, but we don't pull buildings!
Gravity Visualized
Embedded media
Massive objects create a "well" that pulls others in.
This is exactly how Earth's mass pulls everything toward its center!
Magnetism Rules
N
S
Opposites Attract
North and South poles pull together.

Likes Repel
Matching poles push away.
Magnetism in Action
Embedded media
Discover how invisible fields around magnets exert forces.
Remember: Poles that are the same will always push apart!
