Bring some life to you web site by adding photographs of student work, or even the students themselves (if you have permission, of course!).
Google's photo sharing site, called Picasa, is easily integrated into Google Sites - just find the album, copy the URL provided, and paste it into Sites.
Google Sites only supports YouTube and Google Video - for now. Most districts have these blocked, but you could assign home viewing for students.
Just copy the URL of the video and paste it into Sites. It is really that easy.
