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.

Cell Theory

Evolutionary

Theory Charl

aw:

V1/T1 = V2/T2

Page 4: WHY DO WE NEED BOTH? Scientific Theory and Scientific Law

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

Page 5: WHY DO WE NEED BOTH? Scientific Theory and Scientific Law

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:

Page 6: WHY DO WE NEED BOTH? Scientific Theory and Scientific Law

Question:

Is a scientific theory or a scientific law more correct?

Trick question! Both are equally proven to be true through continuous experimentation.

Page 7: WHY DO WE NEED BOTH? Scientific Theory and Scientific Law

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.

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. _________________

Reason: _____________________________________

The galaxies are spreading further apart from each other at a speed = H0 × distance. _____________

Reason: _____________________________________

Gravity associated with any mass curves space and time around it. __________________
