Do any of you guys use anything like that, and is it useful? One of the other teachers has an opinion that some data loggers do everything for the kids, ie produce a continuous graph, and that leaves the kids with nothing to do using their own brains.

Please guys, can I have some feedback. Quite apart from the expense, I ned to know if they really worth it for what we are going to do. I mean, we are recording the temp/salinity/O2 of rock pools over a few hours during the middle of the day. Is using a data logger like cracking peanuts with a sledge hammer?
