KnowItAll
KnowItAll.org is a free multimedia library from South Carolina ETV that families everywhere can tap into. The site hosts educational videos, interactive features, and lesson ideas across subjects like history, science, arts, and career exploration, with a particular strength in content tied to South Carolina and regional stories. Produced by public media, the resources are designed for classroom use but translate well to homeschools looking for primary-source-style footage and local perspectives. Parents appreciate being able to search by grade and topic to quickly find relevant clips to enhance a lesson. Because the interface and catalog reflect its origins as a state project, some topics are more developed than others, but the price—free—is hard to beat. Bookmark favorite series so you can return to them without re-searching.
