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.

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.

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
