UNIT 1
What remains the same in an experiment?
CONTROL
LATITUDE LINES
CONTOUR LINES THAT ARE CLOSE TOGETHER
What is a galaxy?
What is the difference between rotation and revolution?
ROTATION is ONE SPIN on ITS AXIS, REVOLUTION is ONE ORBIT AROUND AN OBJECT
A process scientist uses to test a hypothesis.
SCIENTIFIC METHOD
What lines run East and West?

ZERO FEET
When did the Big Bang take place?
How many times does the Earth rotate in an year?
365
What is changed/manipulated in an experiment?
INDEPENDENT VARIABLE
What lines measure time zones?

Subtract the values of the two index contours, count the lines between them, and then divide.
What does Red Shift indicate?
Galaxy moving away from Earth.
What moon phase does it have to be for a Lunar eclipse?

What is measured in an experiment?
DEPENDENT VARIABLE
What latitude line is zero degrees?

The further a galaxy is moving the faster or slower it moves?
FASTER
What season(s) are the length of days and night equal?
FALL and SPRING
An if-then-because statement about what will happen.
HYPOTHESIS
If you are at 40 degrees North, what it the angle of Polaris?
40 degrees
What are two ways to identify the direction a river flows?
1. Water flows from high elevation to low
2. The source of the river is the direction the arrows point.
What is the relationship between wavelength and strength?
The shorter the wavelength, the stronger it is.
Why do we have seasons?
DUE TO THE EARTH'S TILT ON ITS AXIS.
