I've had an idea that I think would work really well as a Web 2 collaborative project. The idea is that most children aged 8 -12 wil be doing the same basic types of science experiment in the classroom.
I think that it would be great to team up with other classes globally to repeat and replicate experiments to validate results. By doing this I think children would
1. Be excited by science
2. Have to write accurate methodologies that could be followed globally
3. Increase the data gathered to confirm findings
4. Engage with others globally.
I've set up a wiki at www.ks2experiments.wikispaces.com
to outline the possible experiments that people might get involved in. I'm sure that teachers would get lots of great ideas too!
If you think it's a good idea then check it out and add your ideas. At the moment the list is by no means exhaustive but if people start to contribute I'll put down everything that we do here in my classroom.
Hope people get in this project,
