Over Christmas Break I stumbled upon TED (Technology, Entertainment, Design). TED brings together the world's most fascinating thinkers and doers and are challenged to give the talk of their lives (in 18 minutes or less).  I have happily gotten lost in all the videos and ideas that are posted. This one is a hands on demo with play dough and how a pre-k child learned about circuits. I couldn't help but smile about how hands-on and easy this could be for older students who need extra practice with making circuits to help them understand how the concept works plus explain it. Fabulous!
