    3. 4/15/2012 Steps of the Scientific Method Observation State the problem Form a hypothesis Experiment Results/Data Analysis

    4. 4/15/2012 Observations Qualitative observation Focus on the qualities of an object. Ex. Color of an object Quantitative observation Characteristics of an object that can be measured. Ex. Mass, Length

    5. 4/15/2012 State the Problem This problem or question is formed from your observations. This is the question you as the scientist want answered. Also called the “purpose”.

    6. 4/15/2012 Form a Hypothesis The hypothesis is a testable explanation to your problem. “Educated Guess” is not enough. You must be able to test your explanation.

    7. 4/15/2012 Experiment Design an experiment that tests your hypothesis. Control Group: test variables are kept constant “Normal Conditions” Experimental Group: variables are changed
