Control group
A group in an experiment that is taken through the entire experiment except the presence of the independent variable.
Data
Recorded observations.
Theory
An explanation that is broad in scope, generates new hypothesis, and is supported by a large body of evidence.
Bias
A personal viewpoint or preference rather than scientific.
Biology
The scientific study life.
Model
A representation of a theory or process; it can take many forms, including diagrams, graphs, 3D objects, computer programs, or mathematical equations.
Inductive reasoning
A type of logic in which generalizations are based on a large number of specific observations.
Deductive reasoning
A type of logic in which specific results are predicted from a general premise.
Quantitative observation
Observational data gatherer using measurement tools and recorded as a number.
