Scientific Method

• A series of steps that scientists use to answer
  questions and solve problems
• Several distinct steps but not a rigid procedure
• May use all steps or not
• Order of steps may differ or be repeated
• Goal is to have reliable answers and solutions so
  as to gain insight into the problem being
  investigated

5
Steps of Scientific Method

• To get started, observations need to be made
• Use all senses, not just sight, to gather
  information
• Observation is an ongoing process throughout
  investigations

6
Steps (continued)

• Based on the observations made, a scientist will
  form a question
• Hypothesize or make an educated guess
• Form a possible explanation or answer to the
  question
• Must be best guess and testable

7
Steps (continued)

• Test your hypothesis and gather data
• Gather information by making observations
• Earth scientists rely on this form of test most
  often
• Conduct experiments
• Controlled experiments one variable is changed
  at a time

8
Steps (continued)

• Analyze the results
• Create graphs and tables with information from
  research to organize data
• Draw conclusion
• Based on data collect, determine whether
  hypothesis is supported or not
• May form new hypothesis or question

9
Steps (continued)

• Communicate results share
• Share information from investigation with others
  so that they may learn from your experiment
• They may retest or duplicate investigation to see
  if similar conclusion is found

Assessment

• Students are given hypothetical situation. They
  must then complete the steps as if they had
  actually done the experiment.
