NASA scientists frequently use easily represented quantities to describe those that are larger than we can imagine. If the solar system is represented by a football field with the Sun the size of a dime on the goal line, Mars would be a grain of sand on the three-yard line. This imaginary scale is an example of a:
Model
Hypothesis
Constant
Variable

Length; meter
Temperature; degree Celsius
Volume; liter
The variable changed or manipulated during an experiment is known as the:
Dependent Variable
Independent Variable
Constant
Hypothesis
An experimental design consists of an independent variable, a dependent variable, and a carefully selected list of factors that do not vary. These factors that do not vary are known as: KEY WORDS/CHOICES: Constants, repeated trials, data, or materials
Prior to experimentation, scientists examine known factors and form a _________________ as to the result. KEY WORDS: Hypothesis, conclusion, model, scale
