Exploring Circuits

March 9, 2016 at 8:00 am (Science) (, , , , , , , , , , , , , , , , , , , , , , )

We’ve spent some time reading and exploring how to create a static charge.  We now know (I hope we remember) static means to stay still,  We’ve also added current (move), discharge (empty), and insulator (protect) into our repertoire.

We also have predicted and tested items that can conducts electricity vs those that will not.  Last week I attended NCTIES (nerd tech convention) and met a scientist named Steve Spangler, who seems to be on the Ellen Degeneres Show quite a bit.  Cool tidbit, his father invented fake blood.  See any movie ever?  Yeah, that’s his dad’s fake blood on the screen.  He said he was stoked seeing Jaws and thinking how all that blood came from his mom’s nine blenders in their basement.

Anyway  . . .

Thanks to Mr. Spangler, we now have an Energy Stick (find them on Amazon) in which we conducted circuits, safely, through the human body.   We were able to make a class circuit with 4th and 3rd grade combined.  Next we’ll take a scavenger hunt throughout the school to find items that will conduct, allow to pass, electrical currents.  Then we’ll create squishy circuits (home made batches of play-dough) to explore more fun with electricity.  There are recipes for batches that will conduct and those that serve as insulators.  4AA Battery packs  ($2.48 per pack) will be in need – we only have one.  May have to get a Kickstarter or GoFundMe! Enjoy the learning.
