The various steps taken in scientific methods are:

1. To identify the problem- The problem should be identified and defined. The selected problem must have a narrow range and specific aim, otherwise, the solution of the problem cannot be worked out. 

2. To formulate a hypothesis- Hypothesis is a logical explanation which accounts for the observation. It is an important step in the scientific approach. 

3. Testing or experimenting hypothesis- When a hypothesis has been put forward, it is tested by experiments. 

4. Data collection- Observation and identification of the problem is followed by a collection of data, to answer the question relevant to the problem.

5. Finding, the result- Result may be direct or indirect. It should be repeated. 

6. Again retesting- Repeated results are accurately established and they do not need further verification. 

7. To generalise the principle or law- A thoroughly tested fact regarding scientific finding or phenomenon is known as the principle or law. It is found to be reliable for its prediction.
