Scientific Method

The series of steps followed to solve problems, including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

• Observation

• Theory

• Scientific Method

• Prediction

The process of obtaining information by using the senses; the information obtained by using the senses.

• Peer Review

• Control Group

• Hypothesis

• Observation

In science, an idea or explanation that is based on observations and that can be tested.

• Hypothesis

• Prediction

• Experiment

• Peer Group

A statement made in advance that expresses the results that will be obtained from testing a hypothesis if the hypothesis is supported; the expected outcome if a hypothesis is accurate.

• Observation

• Scientific Method

• Observation

• Prediction

A procedure that is carried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth.

• Hypothesis

• Experiment

• Prediction

• Independent Variable

In an experiment, a group that serves as a standard of comparison with another group.

• Experimental Group

• Dependent Variable

• Independent Variable

• Control Group

In an experiment, a group that is identical to a control group except for one factor and that is compared with the control group.

• Control Group

• Experimental Group

• Dependent Variable

• Independent Variable

In an experiment, the factor that is deliberately manipulated, also called the manipulated variable.

• Control Group

• Experimental Group

• Dependent Variable

• Independent Variable

In an experiment, the factor that changes as a result of manipulation of one or more other factors; also called a responding variable.

• Dependent Variable

• Independent Variable

• Control Group

• Experimental Group

A set of related hypotheses confirmed to be true many times, and can explain a great amount of data.
