7. The scientifi c method is a procedure used by scientists to investigate a problem
or answer questions.
8. The scientifi c investigation method is divided into several steps, namely: problem
identifi cation, asking questions, formulating a testable hypothesis, performing an
experiment, data collection and analysis, data presentation, data interpretation,
and drawing a conclusion.
9. Physics uses theories, laws, and principles to describe the universe. These includes
theory of gravity, Hooke's law, law of fl oatation, Pascal principle and the principle
of conservation of energy.
