Independent variable

• A variable that is intentionally changed to observe its effect on the dependent variable.

• The variable or variables that do not change during the experiment.

• The process scientists use to gain scientific knowledge.

• An educated guess that is typically written as an “If…then…” statement.

Latitude

• The distance north or south of the equator, measured in degrees.

• The distance east or west of the prime meridian, measured in degrees.

• 0 degrees longitude.

• Lines of longitude are parallel. Maps are easier to read.
