Project Explorer is a free site designed to bring the world into the classroom. Their site currently has over ten hours of original media with support lesson plans (aligned to National Curriculum Standards or Common Core Standards) in a wide range of subjects: U.S. and World History, Literature, Music, Language, Arts, Social Studies and Sciences.
Lessons are divided by Upper Elementary, Middle School, and High School.
Inside the academic levels, you can select the country you want to learn more about.
Then there is a collection of short media clips to support its lessons; the lessons are even interconnected so you can easily jump from country to country with connected topics.
