Dear Rubi,
Let's work together on this water project. Our 4th grade classes have 19 students each. I have never used ePals to work with another project. I tried using ePals with a class in our area so I could figure out how to teach emailing and being able to see how it worked on a small scale with immediate feedback. We each did a water purification experimented, then discussed it through email. It worked great. That was last year. We have already had email addresses set up for this year's students in hopes of aquiring international ePals. Your classes would be perfect. This is exciting. Take a look at some of the activities associated with this water project. We are definitely looking to understand the use of water by kids in other parts of the world.
We will get this organized!
Diane
