Scientific Inquiry
Science – from the Latin verb scire = “TO KNOW” Science is not a list of facts, it is a constant process
All science is based on two assumptions… 1. The natural world behaves in a consistent and predictable manner 2. Through careful, systematic study, we can understand and explain the natural world’s behavior
The Process of Scientific Inquiry
Hypothesis – a possible explanation based on gathered data. Must be tested, analyzed, and retested If repeated testing fails, hypothesis should be discarded Example: The Nebular Hypothesis
ScientificTheory Very well tested Best explanation for certain observed facts Widely accepted by scientific community ScientificTheory Example: The Theory of Plate Tectonics
Scientific Law Universal and invariable facts of the physical world Can still be disproved if evidence is found! Scientific Law Example: The Law of Gravity
The Scientific Method
The 6 Steps: State the PROBLEM Conduct RESEARCH Formulate a HYPOTHESIS Perform the EXPERIMENT ANALYZE the results Draw a CONCLUSION
Not a linear process it’s cyclical!
Accuracy & Precision are both vital
ACCURACY: capable of providing a correct reading or measurement. In science it means 'correct'. A measurement is accurate if it correctly reflects the size of the thing being measured. PRECISION: exact, as in performance, execution, or amount. In science it means repeatable, reliable, getting the same measurement each time."
