Scientific Methods

What are the steps of Scientific Methods



Ask a Question





Make Observations




Form a Hypothesis




Test the Hypothesis




Analyze the Results



Draw Conclusions




Communicate Results

  • Scientific Methods are the steps used to answer questions and solve problems.
  • They don’t have to be in this order.



  • An observation may be hard to explain or out of the ordinary which leads to a question.
  • Looking for answers may lead to more observations and more questions.



  • Any information gathered through the senses is an observation.
  • Examples: smell, color, shape, measurements of length, volume, time, speed, or temperature



  • A hypothesis is a possible explanation or answer to a question.
  • It is usually stated in an if-then format.
  • It needs to be testable.



  • A controlled experiment tests only one factor at a time and consists of a control group and one or more experimental groups.
  • Every factor must be kept the same except the one factor being tested, called the variable.



  • Organize data into tables and graphs
  • For accuracy, repeat the test several times.



  • Decide whether the results of the experiments support a hypothesis.  If not, find another explanation that can be tested



  • Write a paper.
  • Make a presentation.
  • Create a web site.
  • Sharing information helps other scientists with their own investigations.
  •  In this way, the scientific methods help strengthen our knowledge.
