Scientific Method How Scientists Work!
How Scientists Work: Solving the Problems§ Much of Science deals with solving
problems§ No matter what types of problems
are being studied, scientists use the same problem-solving steps called…
§ The Scientific Method
Scientific Method Definition§ The scientific method is-
§ A logical and systematic approach or process to problem solving.
§ An organized way of using evidence to learn about the natural world.
§ The Scientific method is a body of techniques for investigating and acquiring new knowledge, as well as for correcting and integrating previous knowledge. It is based on gathering observable, and measurable evidence subject to specific principles of reasoning, the collection of data through observation and experimentation, and the formulation and testing of hypotheses.
Scientific Method Listing the Steps§ Make an Observation§ Define the Problem§ Research the Problem§ State the Hypothesis§ Experiment to test Hypothesis§ Collect and Record Data§ Analyze Data§ Draw Conclusions§ Determine Limitations§ Report Results
If needed, Do more investigation

What does the scientist wantto learn more about?
Gathering of information
An “Educated” guess of ananswer to the question
Written and carefullyfollowed step-by-step
experiment designed to testthe hypothesis
Information collected duringthe experiment
Written description of whatwas noticed during the
experiment
Was the hypothesis correct or incorrect?

Scientific MethodAn Overview
The reason scientific work is called “RE-search” rather than just "search " is because it is an ongoing process that often times changes our view of the natural world. It is subject to modification in light of new evidence and new ways of thinking.
