How can we determine the constants of an experiment?

Identify the variables and constants in your experiment. In a controlled experi- ment, a is any factor that can change. Constants are all of the factors that are the same in both the experimental group and the control group.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
