The scientific method


All scientific processes follow a certain process, called the scientific method. These are the steps to follow successfully so that a theory or a phenomena could be proven. 

Everything starts out with a question.  Scientists call this question a hypothesis. To get to the hypothesis there are a few things to do. The first thing is to find something to investigate. Once you have found the actual question, you need to start investigating and observing. 

The more you learn about the topic, the more you will probably want to know about this topic. It is important to learn all you can and to investigate as far as you can to find a possible explanation to your question.  Once you are certain of what you want to achieve, then you need to form your hypothesis.

What is a hypothesis?

A hypothesis is  a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. 

In other words, a hypothesis is the starting point to all scientific investigations. All science starts with something wondering why certain things happen the way it does. This may be in a response to a previous discovery that was made, and gives rise to the new investigation. It is very similar to being a detective. Scientists use a hypothesis to start their investigation, and remember, scientists are naturally curious people. Remember there is still no proof that the hypothesis is proven correct or not.

Test the hypothesis

The next step is to prove whether the hypothesis is correct or not. Scientist will design an experiment to test the theory. The hypothesis will be used to predict the result. The scientist will do the experiment more than once to get a proper result. If the result is the same ever time then the theory can be proven. 

Draw a conclusion

If the result of the experiment is positive every time, then the hypothesis has been proven. If the result did not have the desired outcome then the hypothesis has not been proven. Usually at this stage most scientists go back to the drawing board to work out a different tactic or experiment. They use their findings from the previous experiment to make up a new experiment. 

Report the results

It is important for all experiments to be announced publicly so that other scientists can repeat the experiment to see if it was performed correctly.  Most results are not justly accepted and is reviewed by experts before any finding is accepted. 

If you fail try again

Not all experiments are always a success. When a hypothesis is disproved, other scientists can use the knowledge gained in their own experiment to either reconsider the original theory and create their own hypothesis that will support the evidence.
