<h3>What is the scientific method?</h3>
The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.
For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:
- Observation of a phenomenon
- Questioning the reason or cause for it.
