The Scientific Method involves a series of steps that are used to investigate a natural occurrence.
Problem/Question Observation/Research Formulate a Hypothesis Experiment/Procedure Collect Data Analyze Results Conclusion
Steps of the Scientific Method Problem/Question 1. Problem/Question: Develop a question or problem that can be solved through experimentation.
Steps of the Scientific Method Observation/Research 2. Observation/Research: Make observations and research your topic of interest.
Steps of the Scientific Method Formulate a Hypothesis 3. Formulate a Hypothesis: Predict a possible answer to the problem or question. Example: If soil temperatures rise, then plant growth will increase.
Steps of the Scientific Method Experiment/Procedure Steps 4. Experiment/Procedure Steps : Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).
Steps of the Scientific Method Collect Data 5. Collect Data: Modify the procedure if needed. Include tables, graphs, and photographs
Steps of the Scientific Method Analyze Results 6. Analyze Results Discuss the results. Reference tables and graphs by titles
Steps of the Scientific Method Conclusion 6. Conclusion: Include a statement that accepts or rejects the hypothesis.
What was the independent variable? Ages of the students –Different ages were tested by the scientist
What was the dependent variable? The time it to put the puzzle together –The time was observed and measured by the scientist
What was a controlled variable? Same puzzle –All of the participants were tested with the same puzzle. –It would not have been a fair test if some had an easy 30 piece puzzle and some had a harder 500 piece puzzle.
