Many online resources are available to answer your questions about science, such as ScienceBuddies.org, the science forum at Reddit.com and AskaScientist.com, among other sites. Other "old fashioned" resources are available to provide answers, such as your local library and science professors at your local college.
For more complex questions, consider turning to online forums, where users can post anything that has them stumped and get it explained it in greater detail. Fellow users that are knowledgeable about science can guide you to the answer to your question.
If you are seeking a more personal touch, seek out local resources, such as reference books from a library or consulting a science professor at a college
