Sometimes work means getting to play with some really cool stuff, like sewable, wearable electronics. Every student I showed this to, from grades 4 through 12, immediately saw the possibilities.
This is just a little test kit with a watch battery and a simple on/off switch. I also bought an expanded set with a programmable controller, lights and 3 sensors (light, vibration, temperature).
I think we are going to have some fun with this!
