Scientific Method

This is an educated guess about the outcome of an experiment based on observation and background research.

• Variable

• Results

• Question

• Hypothesis

What are the things in an experiment that are always kept the same to make sure the experiment is a fair test?

• Constants

• Independent Variable

• Dependent Variable

• Control Group

This is the first step of an experiment as is usually based on the things we wonder about the world.

• Analyze the results.

• Ask a Question

• Conduct Background Research

• Form a Hyptothesis

This tool is used to collect and organize data during an experiment.

• Graph

• Report

• Presentation

• Data table

This tool is used to present data from a data table in a visual format.

• Report

• Presentation

• Graph

• Data Table

This is the one thing that is changed in an experiment to test. Everything else in the experiment is kept the same.

• Controls

• Constants

• Independent Variable

• Dependent Variable

This is the part of the experiment that is observed and measured. This part depends on the thing that was changed in the experiment.

• Control

• Constants

• Independent Variable

• Dependent Variable

This part of the Scientific Method is where the scientist discusses the results of the experiment and tells whether their hypothesis was supported or not.

• Conclusion

• Data

• Results

• Science fair board

This is the "recipe" for the experiment that guides how the experiment will happen.

• Results and Conclusion

• Materials List and Procedure

• Data Table and Graph

• Question and Hypothesis

In a controlled experiment, how many variable should a scientist change at one time?

• 2

• As many as they need

• 0

• 1
