How does the teacher encourage his students to become a force for action in the novel, The Wheel on the School?

The teacher challenges his students existing knowledge, asking them what they know about storks, and then asks them to exercise their curiosity: "Will you wonder why storks don't come to Shora to build their nests on the roofs, the way they do in all the villages around? For sometimes when we wonder, we can make things begin to happen."
