Reasonings
Deductive
Inductive
uses general principles to predict specific results
general to specific
Example: Metals conduct electricity and Silver is a metal. So, Silver conducts eletcricity
specific to general
specific observations are used
to construct general scientific principles
Example: rose plant, mango tree, jack fruit and pinus is made up of cells. Therefore, all plants are made up of cells
Hypothesis, Theory and Laws
Hypothesis: reasonable guess
based on observations
Theory: one or more hypotheses that have been supported by repeated testing
Law: single statement that cannot be changed
