What Does Science collect and Organize? Science collects and organizes information to look for patterns and connections.
What do Scientist Constantly do with Scientific Explanations? Scientists are constantly testing, debating, and revising scientific explanations.
What do Scientist NOT do? Pretend they have all the answers.
What are all Scientists Explanations Backed up by? They are backed up with evidence.
What is Scientific Theory? It describes a well-tested explanation about the natural world-explains why something happens.
What are Scientific Laws? Concise descriptions of the natural world-typically backed up by math-describes what happens.

What does Held Constant Mean? The more that is controlled the better the experiment.
What is an Independent Variable? To deliberately change or to manipulate.
What is a Dependent Variable? To be observed or measured or to see the response of the experiment.
What does it Mean to Control? The part of the experiment that is not manipulated and is used as a comparison for the independent variable.
What does Positive Control Mean? A part of the experiment that will not change.
What does Negative Control Mean? The part of the experiment that will not change.
What are Constants? Aspects in the experiment that do not change between control and experimental groups.
What are Confounding Variables? Aspects of the experiment that affect the results but are not the independent variable.
What is Quantitative Data? Descriptive and includes characteristics that can't be measured.
When is Quantitative Data Used? Typically used in the hard sciences like Biology, Chemistry, and Physics.
What is Qualitative Data? Descriptive and includes characteristics that can't be measured.
When is Qualitative Data Used? Typically used in soft sciences like psychology, sociology, and anthropology.
What can the Analysis of Data do? It can either support or refute the hypothesis.
