Achieve has a collection of sample tasks (lessons based on my look at them) that help illustrate how NGSS may be applied. A couple of them directly relate to Environmental Literacy Programming (watersheds). Visit this site to check them out.
These cards can be printed and cut out to help you map out a curriculum's alignment to NGSS. This card deck is also useful in a workgroup or workshop context when multiple educators may be thinking together on how to align lessons to NGSS.
