NSTA Conference in Seattle

The NSTA (National Science Teachers Association) held a regional conference in Seattle from 12/8-12/10/11 and Holly and I were lucky enough to attend.  The seminars attended and booths visited offered up a multitude of great ideas I'll be bringing back to the classroom.  Lots of free loot handed out as well.

Don't you love that Beer's Law is about the concentration of a solution?

Perfect ending to my day - a total lunar eclipse tonight.  Bonus!
