Squishy!

125 The AP class is investigating the resistivity of conductive dough. I was going to make it myself, but then I had jury duty and I had to ask the kids to make it and bring it in. Which they did! It seemed to work pretty well for some groups, but not for others. I will be experimenting on my own at home to troubleshoot some of the issues. Mostly, it had nothing to do with kids using the digital multimeters incorrectly to measure current, though if they did things wrong yesterday they may have blown a fuse and I could not tell. So that is another thing I need to check.

Squeee!

20130305-104336.jpg113 Today the tech ed teacher sent a student to my room with a box full of breadboards and components. It’s like Christmas (or whatever other gift-giving holiday you celebrate)! I’m looking forward to sorting these and figuring out what all the ICs are. I’ve got a very enthusiastic student helper, too!
