1. Parts of an Experiment

3. Question / Problem
All experiments must start with a question or problem.
The question should be specific and test only one variable.

4. Hypothesis
A statement(s) that suggests possible outcomes or answers to the question.
Created after the problem has been researched.

5. Procedure
A list of steps describing how the experiment will answer the question. Variables and constants should be identified.
Changed variable: The thing you purposely change from test to test.
Measured variable: The thing that is affected by changes made to the changed variable.

6. Tell the person next to you the difference between a measured and changed variable.

7. Procedure continued
Constants: Things that are kept the same from test to test.
Control Test: A test that is run the same as all of the others that leaves out the changed variable.

8. Results / Data / Analysis
Results are the observations and measurements made while running the experiment.
Analysis: Graphing or calculating results in order to formulate a conclusion.

9. Conclusion
A statement that answers the question and talks about any uncontrolled variables in the experiment.
New questions are asked and further areas of study are identified.
Uncontrolled variables: Things that occur that may have caused change that you didn’t plan on.
