The SciQ: Science Revealed - Talk About Science Contest is open to all Alberta students in grades 7, 8 and 9. If you know of any, spread the word... Free stuff!
It's cool to see the organizations spending time and resources in an effort to foster the community aspect of these projects, instead of stopping at the public database stage. SciQ has been consistently great at this stuff (with live video broadcasts, interactive sessions with scientists, astronauts, etc...)
Deadline is October 15, 2004.
