HOW DO I IDENTIFY INDEPENDENT VARIABLES?
IT IS ONE PHYSICAL CHARACTERISTIC THAT I CHANGE IN MY INVESTIGATION TO FIND
OUT IF IT WORKED. The book states it is a factor that is manipulated by an
investigator in an experiment. The dependent variable is the factor you
measure as an outcome of your experiment. It depends on the independent
variable you changed. Ex. time (s), mass (g), # of
something, volume (mL), etc.

WHAT ARE THE REASONS FOR THE SEASONS?
1. The tilt of the Earth's axis which allows direct sunlight to hit Northern
Hemisphere during the summer solstice and direct sunlight to hit the Southern
Hemisphere during the winter solstice
2. REVOLUTION AROUND THE SUN

WHAT IS THE LAW OF SUPERPOSITION?
The Principle of Superposition: As layers accumulate through time, older
layers are buried beneath younger layers. If geologists can determine which
way was originally “up” in a stack of layers, they can put those strata in
the correct historical order. Super as a prefix means above
