With 4 other teachers we used Google Docs to set up a master spreadsheet for collecting some data about weather at each of our locations. Each class had a separate Google form that could be filled in to add data to a central spreadsheet.
Each class and teacher could then look at the data in what ever way they wished. It is possible to download a copy of the data from the master spreadsheet.
My class has just started to created some visuals and graphs using some of the data and have blogged about it.
