This rubric is adapted from the NGSS Scientific Practices that are outlined by the standards. I included the NGSS descriptions of the expectation of student knowledge and then broke this down into areas of focus and included four categories of achievement (Advanced, meets the standard, approaching and does not meet). Each skill area and category of achievement has a description to determine where the student falls on the spectrum of achievement. Please see the preview file in order to get a better understanding of the set up. This rubric can be used to collect data and track student achievement in mastering Scientific practices across grade levels. I have also included a grading sheet to use and give to students with areas for feedback.
