Stories with a science focus
Have you ever seen a real life super hero? There are super heros all around us! They may not have super powers or a secret layer, but they may have other qualities that make them special. For example, firefighters are super heros in there own way because they are willing to risk their lives in order to save others. You don't have to be like Superman and have special powers in order to be super. As long as you are willing to put others and their needs before you and your own.
