Global Collaboration between Students

The Center for Interactive Learning and Collaboration (CILC)  is a great site for students from all over the world to work on collaborative Math and Science projects.  "Down the Drain" is an example of a world wide project in which students from all over the world observe then record data on how much water they each use everyday.   Another example of collaborating data is for the students to record and analyze the collected data on their dominant traits.  

In my first grade class, I think it would be educationally beneficial for my students to set up and participate in a project with others in which they would record data based on the kind of rocks found on their school property.  It would be interesting to see the similarities and differences in the "rocks" depending on what part of the world the students lived.
