WHY DO WE NEED BOTH?
Scientific Theory and Scientific Law
Scientific Theory and Scientific Law
The field of biology has more scientific theories that result from research.
The fields of chemistry and physics have more scientific laws that result from research.

Scientific Theory usually explains how something in nature occurs.
It is a misconception that theories turn into laws with enough research.
Scientific Law usually describes an observed phenomenon often with a mathematical formula.
It doesn't explain why the phenomenon exists or what causes it.
Scientific Theory and Scientific Law
BOTH are proven true through continuous
experimentation!
New cells form from existing cellsForce is the product of an
object’s mass and acceleration
Mass can come from energy and energy from mass (E= mc2)
The speed of light in a vacuum is constant and an absolute physical boundary for motion
Is this a scientific theory or a scientific law?
Scientific LAW
Is this a scientific theory or a scientific law?
Part of the THEORY of relativity
Question:
Question:
Is a scientific theory or a scientific law more correct?
Trick question! Both are equally proven to be true through continuous experimentation.
Evolution is a Fact.
Scientists use the term "fact" to refer to a scientific explanation that has been tested and confirmed so many times that there is no longer a reason to keep testing it or looking for additional examples.
With that, the past and continuing occurrence of evolution is a scientific fact.

Evolution Theory is Fact
Label each of the following as LAW or THEORY. Then give your reasoning for your
choice.
The universe began almost 14 billion years ago with a massive expansion event called the Big Bang. _________________
