SM(The Scientific Method)

The Scientific Methoda body of techniques for investigating phenomena, acquiring new knowledge or correcting and integrating previous knowledge

Scientific Method

OBSERVATION

PROBLEM

HYPOTHESIS

EXPERIMENTATION

THEORY

Schematically, the scientific method can be shown as follows:

Observations (world of experience)

Scientific Law(a summary of what have been observed)

Hypothesis(a guess explaining

observations)

Theory(tested hypothesis, not

permanent, can be modified)

Science Process Skills:•Observing•Classifying•Measuring•Inferring•Predicting•Communicating•Using number relationships
