What is it? A procedure (or step by step guide) for developing and/or completing scientific investigations.
Steps of the Scientific Method 1. Purpose 2. Research 3. Hypothesis 4. Procedure 5. Analysis 6. Conclusion
The Purpose… is what you want to learn from the investigation. should be specific. MUST be testable!!! EXAMPLES: Does the shape of a body of water affect the rate of evaporation? Does temperature affect how many blooms a plant will produce?
Research This step identifies what is already known about the topic being investigated (evaporation rates, plant growth). Should use multiple sources! Goal is to find information that will help you predict the results of the investigation.
Hypothesis What do you THINK will happen???? use the research you did to develop a prediction…it should answer the question (Purpose)
Procedure (yes, there’s a procedure within this procedure!!!) This step gives step by step directions for how to test the hypothesis and how to record the results. It should include: 1. Materials (be specific) 2. A detailed “how to” for setting up and completing the experiment with specific instructions for the experimental and control groups 3. Identification of ALL Variables- Independent AND Dependent 4. Data- the results you measured during your investigation (recorded in a table)
Analysis During this step, you determine what they results mean. You MUST: 1. SHOW the data- using 1 or more graphs (be sure to select the appropriate type) 2. Explain the data in a short paragraph detailing the specific measurements you recorded
Conclusion In this step you evaluate whether the results support your original hypothesis. This should be a paragraph that summarizes the experiment and explains in detail whether your prediction was supported by the experiment and “why?/why not?”.
