The process of science is very much one in which you put your thinking on the line, watch an event or phenomenon, and then match the two—pressing and probing until you find the place where there’s a contradiction, or where you encounter something you cannot understand or explain. This process of “looking for trouble” is not something we often value in the classroom. Children are rarely taught that there is anything useful to be gained in examining what you do not know. Yet, for children, this is the essence of how they might learn to find things out for themselves, and thereby become authors of their own knowledge.
