Question everything, and I think better science stuffs. Before you seek for answer, please use your current knowledge to try and find an answer for it first. And that answer of yours should be logical enough to you. For example, if your question was, why rain happened? Your most logical and simple answer would be, because there are water up on the sky. Not because god sneezes and there goes the rain.
Check if your answer is correct. You can check your answer with your teacher, with peers, or simple research on Google.
Ask more question of the same category. Dig deeper. This time, use your logic answer before to add to the information. For example, the last question was why rain happened? You answered: Because water must be up in the sky. The next question should be: How can water be there? Your next answer should be: something or someone brought it there. But if it is someone, then what do they get for bringing water onto the sky? and how? So your next logical conclusion should be something brought it up. Dig deeper and you find out that something is the sun. Just keep asking Why, How, What? to everything, and try to answer them before you seek for help. Faster than you notice, you will develop your logical sense. Don’t rely on single answer to answer all of the question. Don’t rely on a single person to be your mentor. Question everything, and question the answer of the question.
