RESEARCH METHODOLOGY

Detailed explanation-1: -You can use all five of your senses to make observations: your sense of sight, hearing, smell, touch, and taste. Today when making observations outside, don’t use your sense of taste.

Detailed explanation-2: -Of course, we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, fMRI machines, mass spectroscopy, etc.

Detailed explanation-3: -Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing. These tools allow for more precise and accurate observations. Scientists also use equipment to measure things like radiation or pH – phenomena not directly observable.
