Many government organizations and cultural heritage institutions offer lesson plans, free media, and other teaching resources online. This is a short list of free sources for educational materials.
The resources listed here are all available online without a subscription. In the course of your research, you may find other sites on related topics. Here are some things to consider when evaluating whether the information you find is credible.
1. Authority--Who created the site/content? What expertise do they have in the topic?
2. Objectivity--What is the purpose of the site/content (an "About" page can help determine this)? Does it present any bias toward the topic?
3. Accuracy--How does the information correspond to what you already know about the topic? Are sourced cited, and are they reliable?
4. Currency--When was the page created, and when was it last updated?
