More tech!

You all know how much I promote technology for science.  Pasco has an older, hand-held device, called GLX, which is frequently available on eBay for around $100.  The GLX is compatible with the Pasport sensors and collects and displays data.  A manual is available, too.  The GLX is pretty intuitive; if you get stuck, hit the house or home button.  Best if all, it's self-contained.  You won't have to struggle with trying to connect your iPad with Bluetooth to another interface device.  Plug in a senior and start collecting data.  It's another affordable option to add a little technology to your curriculum.
