That's right! Download a free copy of my spreadsheet that correlates the Next Generation Science Standards’ Performance Expectations with an activity for each Expectation for Fourth Grade. The spreadsheet with the lessons is totally free. I decided that I wasn't making very much through TPT and would rather have teachers access and use my resources for free.
Each activity is a link to a lesson correlated to a specific NGSS performance expectation for that grade. If I found a lesson that was for sale that I felt was a strong correlation to the Performance Expectation, I included that as an alternative lesson.
For Ohio teachers, I have correlated the NGSS performance expectations and lesson to the Ohio Science Standards.
Reviews and suggestions for improvement are encouraged!

Thank you for considering my spreadsheet.
