CELLS - GR.6.SC.6.L.14.2

SC.6.N.3.1 Recognize and explain that a scientific theory is a well-supported and widely accepted explanation of nature and is not simply a claim posed by an individual. Thus, the use of the term theory in science is very different than how it is used in everyday life.
SC.7.N.3.1 Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them. (Also assesses SC.6.N.3.1 and SC.8.N.3.2.)
SC.8.N.3.2 Explain why theories may be modified but are rarely discarded.



THEORY
Recognize and explain that a scientific theory is a well-supported and widely accepted explanation of nature and is not simply a claim posed by an individual. Thus, the use of the term theory in science is very different than how it is used in everyday life.

SC.7.N.3.1 Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them. (Also assesses SC.6.N.3.1 and SC.8.N.3.2.)

SC.8.N.3.2  Explain why theories may be modified but are rarely discarded.

A THEORY
EXPLAINS AN EVENT OR PHENOMENON
(A fact or situation that is observed to exist or happen



CELL THEORY


FRANCISCO REDI'S MEAT EXPERIMENT 
SPONTANEOUS GENERATION 
CELLS COME FROM 
PRE-EXISTING CELLS 
REDI'S MEAT EXPERIMENT 
SPONTANEOUS GENERATION









THEORY OF PLATE TECTONICS 









LAW
A scientific law is a statement that describes what scientists expect to happen every time under a particular set of conditions. For example, the law of gravity states that all objects in the universe attract each other. Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. Both scientific theories and scientific laws are developed slowly through repeated observation and experimentation.


LAW =DESCRIBES A PHENOMENON WITHOUT EXPLAINING IT.

Newton's Law of Universal Gravitation 



KEPLER'S LAW OF PLANETARY MOTION 



LAW OF SUPERPOSITION 


 LAW OF CROSS CUTTING -
