The science standards for TN will be changing next year. This document is a chart that shows which concepts were removed from the 3rd grade curriculum, which ones remain, and what new concepts we will be expected to teach.
I created this to help me both this year and next. At the end of this year, I want to teach new concepts that will be considered prerequisite knowledge beginning next year, but that students would normally miss due to the change in standards. I also want to have a chance to start planning over the summer for the new concepts that I have never taught before.
