If you'd like to know why, please read on:

A scientific question is a question that can lead to a hypothesis.  A question is considered scientific if one can design an investigation to answer the question. To put it simply, you can answer the question through testing and experimentation. These type of questions are based on scientific ideas, thus supernatural, morality, opinions and the like are not considered scientific because they are not observable.
