My boys are fascinated by Australia! (Who isn't, right?) Because we follow a heavily interest-led approach to education, per their request, we have studied this small continent a few times during our years of homeschooling.
By the third time through, I felt we had exhausted our resources! We had already read all the books we could get our hands on including those in BookShark's Eastern Hemisphere Level 5 for ages 10-13, watched (and rewatched) all the movies and films about Australia I could think of, and even tried several authentic Australian foods and recipes.
