Wikipedia is an information wonderland. But is it good information? Wikipedia gets a bad reputation at times because of how it's set up: with anyone having the ability to add and edit entries. However, Wikipedia isn't just a nonsensical website. It has things in place and set up to help the information seeker find quality, trusted sites. So instead of shunning wikipedia immediately and outlawing it as an option for researching, teach kids good digital citizenship and show them how to look for and analysis wikipedia articles for their quality and trustworthiness.
Padlock: there is a padlock on some wikipedia entries. The meaning of these padlocks can be found HERE. Padlocks restrict who can make an entry and who can edit an entry, making it a much more trusted source of information.
Good articles: Articles with a green plus sign in the middle of a circle are considered "good articles" and can be trusted.
