Graspr-school based uses

I was intrigued by the description of the website Graspr that claims to have "how to" videos.  I found the section under education and then went to elementary.  I found some videos about colors and telling time, but I also found many that could be inappropriate for the classroom.  I like the idea of introducing students to how to videos, but I think that this sight needs to have many more videos before it can be really useful.  The best bet might be to create your own videos using your classroom to help educate others.
