Scientific Method Vocabulary

Scientific methods

• a possible explanation for a problem using what you know and what you observed

• The pattern of investigation procedures

• tests the effect of one thing on another using a control

• QUANTITY that can have more then a single value

Hypothesis

• a possible explanation for a problem using what you know and what you observed

• The pattern of investigation procedures

• tests the effect of one thing on another using a control

• QUANTITY that can have more then a single value

Experiment

• a possible explanation for a problem using what you know and what you observed

• The pattern of investigation procedures

• tests the effect of one thing on another using a control

• QUANTITY that can have more then a single value

Variable

• a possible explanation for a problem using what you know and what you observed

• The pattern of investigation procedures

• tests the effect of one thing on another using a control

• QUANTITY that can have more then a single value

Dependent variable

• a variable changed to see how it will affect the dependent variable.

• a factor that does not change

• value changes according to the changes in the other variable

• standard by which the test results can be compared.

Independent variable

• a variable changed to see how it will affect the dependent variable.

• a factor that does not change

• value changes according to the changes in the other variable

• standard by which the test results can be compared.

Constant

• a variable changed to see how it will affect the dependent variable.

• a factor that does not change

• value changes according to the changes in the other variable

• standard by which the test results can be compared.

Control

• a variable changed to see how it will affect the dependent variable.

• a factor that does not change

• value changes according to the changes in the other variable

• standard by which the test results can be compared.

Bias

• an explanation of things or events based on knowledge gained from many observations and investigations

• represents and idea, event, or object to help people better understand it.

• state about what happens nature and that seems to be true all the time.

• occurs when a scientists expectations changes how the results of an experiment are viewed.
