I'm now in the middle of planning a project involving web conferencing with a bunch of year 1 children. I'm going to split the children up. One group with be here on Earth. The other bunch will be aliens, who using the wonders of webcam technology will communicate with Earthlings at the Mossford Green Space Centre ( Like Cape Canveral only in East London).
The Aliens will need to think about sets, costumes and make up. They will also need to think about creating names and background histories.
The whole conversation will be recorded and there will be a video blog on a weekly basis.
