Wikipedia is a free encyclopedia that anyone can edit. It is a really useful source of information, as long as you know what it is and how to use it critically. Here are a few facts about wikipedia:
- There are wikipedia pages on almost everything, from big ideas like Physics to silly things like comic book villains
- Wikipedia is written with an adult audience in mind, so it might use high-level vocabulary and be hard to understand
- Because anyone can edit it, the articles tend be very long and detailed. It's great for experts, but can be overwhelming for most people
- Because anyone can edit it, there may be FALSE INFORMATION! This stuff usually gets fixed pretty quickly, but if you're unsure you can check the references (they look like this1). Every fact should have a reference that says where the information came from.
