Using the Next Generation Science Standards Site, I have compiled the Disciplinary Core Ideas as well as the performance expectations for course 1 middle school (6th grade).
The document also gives the Practices and Core Ideas / Practices and Crosscutting Concepts next to the performance expectations.
I used the suggested model course mapping from the NGSS website. See page 11 of the following link to see the NGSS suggested model course mapping.
The document was made in Excel and is editable.
