In a surprise to you...parents and teachers do not know everything. There is no one and no machine with all of the world's knowledge. We learn bits and pieces throughout our lives and continue learning for our entire lives, sewing the information together. It's okay to say you don't know the answer to something. There could be multiple answers, varying ways to reach answers, or no answer at all. If we don't know an answer, we can seek help, use technology, and work together to find one.
