Part of the learning process is discovery, so you can actually incorporate finding things out into your lesson plan. The best teachers I know explain things to students in a way that informs them and encourages them to seek out the tools they need to find even more information on their own.
Certain things, such as academics, must be taught to children. But self discovery is an important part of the learning process. Children must be allowed to discover some things for themselves because only then will they really understand the process of how and why they work. This is especially true in regard to many social situations.
