The Scientific Method

• The scientific method is a logical approach to
  problem solving by using a set of ordered steps.
  The number of steps may vary depending on the
  type of problem.
• This method is used mostly by scientists, but can
  be successfully applied to almost any problem.

The Scientific Method

• There are five basic steps to the process
  scientists use in their investigations.
• State the problem
• Hypothesis
• Testing
• Analyze results
• Conclusion

The Scientific Method
Step 1 State the problem This step is usually
completed by making observations, collecting
data, taking measurements, and weeding out
useless information. You cannot solve a problem
without knowing what the problem is!!

The Scientific Method
Step 2 Form a hypothesis A hypothesis is a
testable statement which some people refer to as
an educated guess. It is a possible solution
to the problem and serves as a basis for making
predictions and carrying out experiments.

The Scientific Method
Step 3 Testing Testing the hypothesis requires
performing an experiment that provides data to
support or refute the hypothesis.

The Scientific Method
Step 4 Analyzing Results The data collected
from the experiment must be analyzed. Tables,
models and graphs are used to show how data is
related and to help clarify the results.

The Scientific Method

• Step 5 Conclusion
• There are only two possible conclusions after
  analyzing the results.
• The data support the hypothesis.
• (Remember, a hypothesis can never be proven with
  one experiment)
• The data refute the hypothesis.
• At this point, more research needs to be done,
  the hypothesis revised, and a new experiment
  devised.

The Scientific Method

• Sometimes progress in science happens because of
  accidental discoveries, but the most significant
  advances result from carefully planned
  investigations.
