Everybody asks science questions, especially young children and people who are at school. Dealing with science questions can be hard if you lack the specific knowledge needed to answer them in a satisfactory way.
Sometimes guessing the answer to science questions can have a detrimental impact far greater than just saying "i don't know".
The internet is a great resource for finding the answer to common science questions but it shouldn't be taken as 100% reliable as frequently facts are misquoted and references aren't supplied for cross-checking.
The best way to get answers to science questions is to hire a private science tutor. A private science tutor will know the syllabus and will be able to quide you through the actual science of the answer rather than just tell you what the end result is.
Asking people who don't have a science background to teach you science is like asking your dog to fix your car - they frequently won't even understand the question!
