-
Common procedures used by scientists to gather information used in problem solving and experimentation
Scientific Method
-
The variables that must be kept the same
Constants
-
In an experiment the group whose conditions are being changed
Experimental Group
-
The group that does not have the variable being tested
Control group
-
Testable explanation of a question or problem
Hypothesis
-
Description of the behavior of a variable or the relationship between two variables
Trend
-
A final statement summing up the results of an experiment, rejecting or accepting the hypothesis
Conclusion
-
Variable in an experiment the scientist purposely changes; variable being tested in an experiment; found in the x-axis
- Manipulated or Independent Variable
- (MIX)
-
Variable in an experiment that the scientist wants to observe; variable being measured as a result of tested variable; found in y-axis
- Dependent or Responding Variable
- (DRY)
-
Data from observations that do not contain numbers
Qualitative Data
-
Data from an experiment containing numerical measurements
Quantitative Data
-
The interpretation of an observation based on prior knowledge
Inference
-
An inference about future events based on current evidence, past experience or knowledge
Prediction
-
How close a measurement is to the actual value
Accuracy (Accurate)
-
How close measurements are to one another
Precision (Precise)
-
Explanation of a set of observations about the natural world
Theory
-
Description of what is actually seen, heard, felt, tasted and smelled
Observation
-
Series of steps in an experiment
Procedure
-
Things that are needed in an experiment
Materials
-
Facts, information, measurements, observations gathered in an experiment
Data
-
A set of procedure to test a hypothesis
Experiment
