Knowitall.org

Once in a while I stumble upon a website that should get far more attention than it does.

The site from Knowitall.org is one of them.
It's ETV's educational Web portal, and is filled with all sorts of interactive items for K-12 students, teachers and parents. In fact, many of them are websites that can be used as a whole to cover a subject.

The diversity of the subjects is large, so there's something for everybody.

There's a good mix of fun and educational content. For example the song: Wash hands, and the manual for writing a Haiku.

Have a look yourself.
