There are four questions in ma nishtana that the children are supposed to ask. We ask how come this night is different than all the other ones EX:) 1) Why do we only eat masa when usually we have masa and chametz. 2) How come on other nights we have all different vegetables but this night we have maror the bitter herbs? 3) How come on other nights we sit however we want but on this night we only lean to the  left? 4) How come on all the other nights we dip once but on this night we dip twice?

During the Pesach seder, the adults should say the story and the children should ask questions about the story. When we're at the Pesach Seder we should feel like we are in esiat mesraeem and feel like we're leaving Egypt itself not just the four fathers. The point is when the children ask the question they would feel more involved. The reason for the ma nishtana is for the children who are too shy to ask questions or don’t know which questions to ask about the freedom of our ancestors. They now have a chance to see the type of questions that may be asked.
