Let it Go and Electricity

Here was one of the popular videos from the week:

Let it Go Christmas Lights

Questions we asked in class are:
1.  Where does electricity come from?  What is it?
2.  How does electricity work?
3.  What is a circuit?
4.  How can we tell if a circuit is opened or closed?
5.  What makes some lights brighter than others?
6.  How would we set up a light show?

We'll learn the answers to these questions soon!
