In one of my recent wanderings to find exciting current events in science, I stumbled upon this article from Wired Magazine's blog, written by Jonah Lehrer. I've copied the final paragraph below, but recommend reading the entire post, as it includes similarly profound ideas about children's minds and how we can best help them follow a path of lifelong learning.

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.
