2.  Discovery process  Step 1 – Make Observation - Qualitative: non-numerical - Quantitative: numerical

3.  Formulating hypothesis - possible explanation to a problem

4.  Perform experiment - test of the hypothesis  Experiment must be controlled -means you can only look at one variable at a time

5.  Analyze results of the experiment -results called DATA  Graphs are used for showing theses relationships  The independent variable goes on x-axis, the dependent variable on the y-axis

6.  A “best fit” line is drawn between the data points  Extrapolation – when a point beyond the actual data collected is estimated from the best fit line  Interpolation- when a point between two collected data points is estimated from the best fit line

7.  As one variable increases, the other increases

8.  As one variable increases, the other decreases

9.  Conclusion - if experimental evidence confirms the hypothesis a theory is formed (also called a model) - Natural Law: statement of reoccurring observed behavior - natural law state observation, theory tells why the natural behavior occurs
