This incredibly powerful resource includes a searchable archive of "stories" with multi-media content for learning in the humanities. There is also a maker space for students (and parents) to create their own stories. It's a great place to research and write about anything! The archive of stories and sources is free, and membership (including curriculum and assignment tools) is very reasonably priced.
