The moral is that parents and teachers must navigate the fine line between giving kids a taste of knowledge – the universe is not all mystery – while at the same time preserving a sense of ambiguity and uncertainty. When we explain things to kids, we shouldn’t pretend that we have all the answers. We shouldn’t turn science class into a dry recitation of facts that must be memorized, or only conduct experiments in the classroom in which the results are known in advance. Because it’s the not knowing – that tang of doubt and possibility – that keeps us playing with the world, eager to figure out how it works.
