THEORY VS LAW (8th Grade)

(CLICK HERE) THEORY VS. LAW (DIGITAL LESSON)

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.)
Also Assesses

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

A scientific theory is a well-substantiated explanation of some aspect of the natural world that has been gained by going through the scientific method and repeatedly tested and confirmed through observation and experimentation.

THEORIES = EXPLAIN AN EVENT OR PHENOMENON

Phenomenon- A fact or situation that is observed to exist or happen, or explanation .

ATOMIC THEORY

SC.8.P.8.1 Explore the scientific theory of atoms (also known as atomic theory) by using models to explain the motion of particles in solids, liquids, and gases.

SC.8.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of subatomic particles (electrons surrounding a nucleus containing protons and neutrons).

NEBULAR THEORY

BIG BANG THEORY

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.
