This is a seven minute Youtube video on the Next Generation Science Standards (NGSS). This brief introduction gives an exellent overview of the NGSS and is well worth the time.
The video is done by Paul Andersen, a biology teacher in Bozeman, Montana. He is excellent! Has many other videos, mostly biology related; 247 videos as of this writing. Highly recommended!
