2. Invent a tentative description, called a hypothesis, that is consistent with what you have observed.

3. Use the hypothesis to make predictions.

4. Test those predictions by experiments or further observations and modify the hypothesis in the light of your results.

5. Repeat steps 3 and 4 until there are no discrepancies between theory and experiment and/or observation.

It is based on gathering data – observable, empirical and measurable evidence subject to specific principles of reasoning – through observation, experimentation, and the formulation and testing of hypotheses.
