• empirical evidence

• science

• experiment

• theory

A pattern, plan, representation, or description designed to show the structure or working of an object, system, or concept.

• science

• model

• law

• mean

An organized procedure to study something under controlled conditions, and to observe their effects, in order to gain new data.

• metric system

• accuracy

• experiment

• independent variable

evidence is gathered from experiments run in a controlled environment, such as a laboratory. The important thing is that the experiment is repeatable, and will provide the same results each time it is carried out.

• law

• precision

• anecdotal evidence

• empirical evidence

evidence is based on personal experience of one person or small group of people. It cannot be relied on to provide factual evidence.

• empirical evidence

• anecdotal evidence

• model

• observation

A system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation.

• theory

• scientific notation

• accuracy

• simulation

A descriptive statement or equation that reliably predicts events under certain conditions.

• science

• hypothesis

• dependent variable

• law

The process of obtaining information by using the senses.

• experiment

• observation

• mean

• law

An idea that leads to scientific investigation and can be testable through experimentation and observation.

• independent variable

• accuracy

• hypothesis

• simulation

A variable that is changed in an experiment.
