Scientific Method
LEARNING COMPETENCY:
The learner identifies the components of an investigation: research problem, hypothesis, method for testing hypothesis identifying
independent/dependent variables), and conclusions based on evidence

What is Scientific Method?
• It is a step by step procedure used by the scientist to solve a problem.
• It includes, observation,
statement of the problem,
hypothesis, experimentation,
and drawing conclusion, such
theory and law.

Theory- are hypothesis extensively tested and used to describe model. Theories are also questioned and tested by new experiments. They may be modified in order to fit new or previous results.Law-A general principle or rule that is assumed or that has been proven to hold between expressions.

Science Process SkillsWhen you make scientific investigations, you are demonstrating basic and integrated science process skills.

The Discovery of the Painter
• The painter had observed that when two or more color is mixed, an new color was formed.
Prepared by: D. C. Tabinga, Jr.
The Discovery of the Painter
• Then he thought of mixing red and yellow. He was curious about what color will be formed after mixing.
Prepared by: D. C. Tabinga, Jr.
The Discovery of the Painter
• He wrote his assumptions on what color will it make.

The Discovery of the Painter
• After several trails he concluded that mixing red and yellow produces ORANGE

Work with a Problem by
yourself?
LEARNING COMPETENCY:
The learner conducts simple investigations using processes involving mixtures common to the locality.
The learner chooses an interesting topic for investigation.

Fair Test
LEARNING COMPETENCY:
The learner describes what is meant by fair test.
The learner recognizes that the design of an investigation should show fair testing.
Prepared by: D. C. Tabinga, Jr.
What is a fair Test?
A fair test is an experimental design thathelps ensure that only one factor or variable inthe experiment is changed while keepingeverything else the same.
Prepared by: D. C. Tabinga, Jr.
What is a fair Test?
Conducting a fair test is one of the bestpractices of experimental research because ithelps prove that the outcome is attributed onlyto the manipulative variables.
Prepared by: D. C. Tabinga, Jr.
The Dependent and the Independent Variable
• Variables- The factor that can be changed in the experiment.
• Experimental Variables-is allowed to change in order to determine the effect.
• Dependent Variable-are the variables allow changes in amount, treatments, or any applications.
• Independent Variable -are not subject to change.
Prepared by: D. C. Tabinga, Jr.
Isolation
• Isolation The scientist separates the material being studied from everything else
• Control – in any study, the part of the experiment or test that provides a standard of comparison with which to confirm or rule out errors in the experiment.
• Controlled Experiment- where the researchers isolate and test the effect of the variable.
• Data-information gathered

Science vs. Superstation
The Myth Vs. Science
MYTHS
• The world is flat.
• The center of the universe is Earth.
• Dragons are monsters.
• The race of man came from Eve and
Adam.
The Myth Vs. Science
FACTS
• The world is round.
• The center of the Solar System is the Sun.
• Dragons are reptiles and they are not big.
• Man came from apes.
Superstitious Vs. Facts
Superstitious Belief
Traditional belief, rituals, and customs that
is being followed or applied without any
scientific bases.
Facts
Any information gathered from scientific
experimentation, result of any observed
phenomenon or event.
