The scientific method is used by scientist and others to solve problems.  See the detailed table below containing more information about this topic.


THE SCIENTIFIC METHOD

 Step 1:

State the Problem

 You cannot solve a problem until you know exactly what it is.

 

 My Problem is"I need a date for Friday Night".

 Step 2:

Research the Problem

 What will it take to solve my problem?

 What do I know, and need to know, about my problem?

 

 To solve my problem, "I need someone to take out Friday NIght".

    Who can I take?

              -Examine the possibilities.

              -Eliminate poor choices.

              -Consider likely choices.

 Step 3:

Form a Hypothesis

 A possible solution to my problem. 

 The simplest solution is often the nest solution!

 

"My date will be (Name)".

 Step 4:

Test the Hypothesis

 Perform an experiment to see if your hypothesis works.

 

 "Ask (Name) for a date Friday Night".

 Step 5

Draw Conclusions from

the Data

 Data are the results of an experiment

 In its simplest form, there are only two possible conclusions:

 

Conclusion 1  If you hypothesis was correct, you now have a date for Friday.

PROBLEM SOLVED

Conclusion 2  If your hypothesis was incorrect, the experiment failed.

DON'T GIVE UP!

 

DO MORE RESEARCH

-What was wrong with your original hypothesis?

-Did you make a poor selection?

-Was your experiment flawed?

-Form another hypothesis based on additional research

-Test the new hypothesis

Continue this process until the problem is solved!
