Scientific Method
Scientific MethodThe Scientific Method is a method of
problem solving involving observation to test a hypothesis.
Step 1Purpose/Question
Your first step is to determine a problem or question so that you know what you want to test.
Research / Observation
After deciding on your question, you should complete some research to discover what background information is needed to perform the experiment.
Step 2Hypothesis
Based on your research make an educated guess that answers your question.
Step 3Procedure/Experiment
Make a list of directions for testing your idea or hypothesis through a controlled investigation. These should be detailed so that another person can follow your directions and perform the same experiment.
Control
You will need a control which is a standard against which other conditions can be compared in an experiment.
Variable
You will also need a variable which is the factor being tested.

Step 4Materials
Make a list of all materials used to conduct your experiment.
Observation
While completing your experiment you will record findings.
Step 5Results/Data
As you perform your experiment, collect data. Using this data make a judgment or opinion inferred from relevant facts; a final summary.
Step 6Conclusion
After completing your experiment you will make a judgment or opinion inferred from relevant facts. Write this as a final summary.

Question 5 - Use your flashcards to answer these questions.What part of an experiment is kept in normal
circumstances, so that the scientist has something to compare their test subjects to?
Question 6 - Use your flashcards to answer these questions.An educated guess that has not been proven,
