This document discusses two types of research questions - big questions and smaller questions. Big questions are open-ended, require longer answers, and direct overall research. Examples include "How do airplanes fly?". Smaller questions support the big question and usually start with who, what, where, when. They have shorter, more specific answers. Examples include "Who invented the first airplane?". The document provides guidance to students on developing questions about the author Jeff Kinney for a research project.
