iScience Project is clearing out their stock of Serial Hobos for really low prices, but you have to act before August 25th, 2006.
Officially it's an Auction with a minumum bid of $18 for a kit or $35 for buy it now (normally $139/kit).
That buys you a small device (half the size of a deck of cards) that will record temperature, light, and humidity. It also comes with an external temperature probe on a 6' lead (so you can take two temps at the same time).
Hobo's are pretty cool. You plug them into the computer and use their software to set them up (what type of data to record and how often a reading is taken). Then you unplug it and leave it where you're collecting data. Once done you plug it back in and download the data to the computer.
These are cheap enough you could send them home with your kids for at home experimentation. There are hundreds of activities on the iScience Project page to use with Hobos if you can't think of any yourself.
They also have a loaner program so you can borrow Hobo's before you buy and there is usually some sort of contest you can enter to win a Hobo as well.
I've played with some Hobo's and will be more than happy to share my thoughts with you. AFAIK the serial ones are Windows only. They do sell USB ones that will work with Mac OS 10.2 or later (but they'er not super cheap right now)

FAQ - What is demo stock at The HOBO Depot and Onset Computer Corporation? Any product that ever has been returned used or unused and any product that ever had a blemish or misprint on the casing. All of our demo stock has fully functioning components that we warrant for a full year. If any product is not working we guarantee we will replace it ASAP. All of these products come with a PC serial port connection and serial port cable (9 pin trapezoid). You would either need an available serial port (older computers have them) or a new serial to USB Keyspan adapter ($39 at any store that sells computers). All of these kits come with free PC Boxcar 4.3 software which is compatible with Win98 to WinXP and one free serial (9 pin) cable and one new battery.
