I have been working with my colleagues trying to come up with a comprehensive teaching module that can be taught to school kids. Most of them are at the stage of idea generation. A few ideas like conducting science demo, awareness video on global warming are implemented at least once.
The more I read, the more ideas I get, and they leave my brain almost as fast as they enter. So, I have logged my ideas in my blog (follow link).
Take a look and provide constructive comments, improvements, implementations, contacts, complaints

Talks about ICED and more importantly to me, indicates that making chalk can be easy, and combined with day-to-day work!
