Scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.[1] To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning.[2] In 1021 CE, Ibn al-Haytham introduces the experimental method and combines observations, experiments and rational arguments in his Book of Optics.[3] There are five major steps in the scientific method: Observe, Hypothesize, Predict, Experiment and Reproduce.
