Term
Problem Statement
Definition
question, observation and description
Term
Questioning/gathering facts
Definition
gathering of facts and clues, questions answered by experiments, use prior knowledge and experience
Term
Hypothesis
Definition
educated guess, tentative explanation based on testable factors
Term
Testing/experiment
Definition
to determine if hypothesis solves problem
Term
Conclusion/explanation
Definition
a hypothesis that has been thoroughly tested, yes or no answer
Term
theory
Definition
well established principle that has passed lots of tests that most consider true, more tests and experiments are done and scientific explanation created. not 100% true, cant be.
