Scientific Method and Inductive and Deductive Reasoning

Author: Diana Siliezar

I can differentiate between Inductive and deductive reasoning

I can recognize the components of the scientific method


The scientific method is a flexible process.  It is important to understand that most of the time the scientific process is not a rigid sequence of steps.  Most of the time scientists start start an experiment and then realize that they need to refocus and collect more data via observations prior to designing their experiments.  Scientists often change the direction of their research based on new questions.  

It is important to understand inductive and deductive reasoning in order to have a good understanding of how scientists use science reasoning.

In inductive reasoning we make observations and derive generalizations.  For example, All organisms are made up of cells.  It took much microscope work observations to come up with the cell theory. So specific observation to generalized statement. Induction is based on observations. 

In deductive reasoning one looks at general statements to specific results that would be expected based on a theory. The result is based on a premises.  If birds have feathers and beaks and eagles are birds then eagles have feathers and beaks.  Deduction helps you to make predictions of what you will discover if one of the premisesor hypothesis is true. Deduction is hypothesis based.
