1. Scientific Method

2. All scientific investigations begin with observations in nature
All scientific investigations begin with observations in nature. Once observations are made the scientific method is the steps taken to investigate natural occurrences.

3. The Scientific Method State the problem (in the form of a question)
Gather information (research)
Form a hypothesis
Test the hypothesis
Analyze the data
Draw Conclusions
Repeat the steps
The Scientific Method

4. Develop the a question or problem that can be solve through an experiment
State the Problem

5. Gather information Research you topic of interest.
Use reliable sources to find information (ex. encyclopedias, scientific journals).

6. Predict an answer to the problem
Predict an answer to the problem. The hypothesis is an educated guess, that should be based on research.
Write an if, then statement.
Ex. If the water faucet is open, then the amount of water flowing will increase.
Form a Hypothesis

7. Test the Hypothesis Develop an experiment
Develop and follow a procedure
List the materials
Make sure the outcomes are measurable.
Test the Hypothesis

8. Test the Hypothesis cont.
Experiments contains two variables or factors being tested:
Independent(Manipulated) Variable- the factor intentionally varied by the experimenter
Dependent (Responding) Variable- the factor that may change as a result of the changes made to the independent variable
Experimental Group- The group being tested.
Control Group- The group that serves as a standard of comparison. The control group undergoes the same conditions as the experimental group except for the variable being tested.
Constants- All the factors that are kept the same through out the experiment
Test the Hypothesis cont.

9. Analyze the Data Record Observations
Organize data in tables and graphs
Interpret the data.
Analyze the Data

10. Make a statement to either accept or reject the hypothesis
Make recommendations for ways to further study or to improve the procedure
Draw Conclusions

11. Reduces bias
Eliminates errors and mistakes
