2.
principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses
3.
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

three-dimensional representation of a person or thing or of a proposed structure, typically on a smaller scale than the original.
6.
a well-substantiated explanation of some aspect of the natural world, based on a vast body of evidence that has been repeatedly tested and confirmed through observation and experimentation.
7.

the factor that a researcher manipulates or changes to observe its effect on another variable
14.
the factor that is measured and is expected to change in response to changes in the independent variable
15.
A line of best fit is a straight line drawn on a scatter plot that best represents the linear trend of the data points.
16.
an association between two variables where a change in one variable results in a proportional, constant rate of change in the other, which is graphically represented by a straight line
17.
describes how one variable changes in proportion to the square of another
18.
describes how two variables move in opposite directions: as one variable increases, the other decreases
