Mo.1-L1b : What are Scientific Theory and Scientific Law?

There are many results of scientific inquiry, and a Let’s Begin
few possible outcomes are the development of new
materials and new technology, the discovery of new
objects and events, and answers to basic questions.

Mo1-L1b What are Scientific Theory and
Scientific Law?
KEY CONCEPTS:
1. How are a scientific law and scientific theory
different?
2. What is Critical Thinking? Scientific Theory
Vocabulary A-Z A scientific theory is an explanation of observations
or events that is based on knowledge gained from
Let us learn some vocabulary many observations and investigations.

A scientific theory does not develop from just one
hypothesis, but from many hypotheses that are
connected by a common idea.
Scientific Theory
an explanation of observations or events that is
based on knowledge gained from
many observations and
investigations.

An elastic collisions is a collision in which no kinetic
is lost. Therefore, kinetic energy among gas particles
is conserved.
