Notes: Scientific Method and Models
Scientific Method
______________________________________________________________________________________
______________________________________________________________________________________
-Organized process
-Generally, 6 steps
-Use all or some
-Repeat steps
Steps
1. __________________________
-After making observations
-Only 1
2. __________________________
-Use what you know
-If…then
-Testable
-Not right or wrong
-Possible answer to question
3. __________________________
-Design an experiment
-Controlled
-Variables
-Measurements/Observations/Data
4. __________________________
-Calculations
-Tables/graphs
-Relationships
What is data?
______________________________________________________________________________________
_________________________________________________________________________________________
5. __________________________
-Again: not right or wrong
-Does the data support your hypothesis?
-A guide for future investigation
6. ___________________________
-Important!
-Papers, presentations, web site
-Keeps science going!

Models
-A model is _____________________________________________________________________________
-Uses something familiar to help you understand something that is not familiar.
-The three types of models are: ______________________________________
_______________________________________
_______________________________________
Physical Models
Mathematical Models
Conceptual Models
Scientific Theories
-A theory is an __________________________________________________________________________
-Supported by repeated tests
-Can predict what may happen
-Scientists use models to explain and change their theories
-Examples: Big Bang Theory, theory of evolution
Scientific Laws
-A law is ________________________________________________________________________________
-When a model correctly predicts results of many different experiments
-Tell you what happens- not why
-Examples: law of the conservation of mass
