(Q3) WEEK #2 / ACTIVITY #1

The SCIENTIFIC METHOD

The SCIENTIFIC PROCESS

Steps of SCIENTIFIC INVESTIGATION

The SCIENTIFIC METHOD

• OBSERVATION of a PHENOMENA

• GATHER DATA

• DEVELOP A QUESTION

• TEST

• OBSERVE

• GATHER MORE DATA

• REFINE QUESTIONS into HYPOTHESIS

Multiple Choice

What does "phenomena" mean?

• unobservable fact

• observable fact or event.

SCIENTIFIC METHOD

-There is NO pre-determined scientific method.

-There is NO pre-determined order to the scientific method

-The scientific method is FLEXIBLE and depends on the phenomena that you are studying.

Multiple Choice

Can the steps in the scientific method vary, or change in order depending on the phenomena being studied?

• No, the steps of the scientific method can never be changed.

• Yes, the steps of the scientific method can be changed.

Scientific Terminology

A hypothesis is a proposed explanation for a phenomenon

Multiple Choice

What is a scientific hypothesis?

• A proposed explanation for an observed phenomena.

  
  

  It has NOT been accepted to be THE only explanation.

• An observation of a phenomena

Scientific Terminology

THEORY = a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena. 

-plausible = makes sense, rational, logical

-principle = fundamental truth that serves as the foundation for a system of belief or behaviour or for a chain of reasoning.

Scientific theories are based on repeated observations by many scientists in different fields of science.

Multiple Choice

Scientific theories are?

• proposed explanations of an observed phenomena.

• based on repeated observations by many scientists in different fields of science.

Scientific Theory is NOT a Scientific LAW

a scientific law is the description of an observed phenomenon.

It doesn't explain why the phenomenon exists or what causes it.

The explanation of a phenomenon is called a scientific theory.

It is a misconception that theories turn into laws with enough research

Multiple Choice

Can a scientific hypothesis become a scientific theory?

• Yes. With sufficient observation, testing, data collection by many scientists, a scientific hypothesis can become a scientific theory.

• No. A scientific hypothesis can never become a scientific theory.

Multiple Choice

Can a scientific theory become a scientific law?

• Yes. With enough testing, data collection and over long periods of time, a scientific theory can become a scientific law.

• No. Scientific theories are the best explanation for some observable phenomena. Scientific laws are basically facts that are accepted by "science."
