The document outlines the scientific method and models. It describes the scientific method as having 6 general steps: making observations and questions, developing hypotheses, conducting experiments, analyzing data, forming conclusions, and sharing results. It defines models as simplified representations that help explain phenomena. The three types of models are physical, mathematical, and conceptual models. Scientific theories are explanations supported by evidence that can predict future results, while scientific laws describe what will occur under certain conditions based on repeated experimental evidence.

-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

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
