I am currently chair of chemistry and biochemistry at Minnesota State University Moorhead, where I have taught physical science to elementary education majors, chemistry, physics, astronomy, and teacher methods for the last 17 years. Prior to this I taught science and math K-12 in Virginia and Minnesota.

While I strongly agree that providing a hands on experience first (5E inquiry learning cycle) is the best approach for many topics, there is also a big danger the approach many of you are discussing. Frankly, one of the reasons Americans can't science is that their elementary teachers fail to teach physics, chemistry, engineering, etc. even when there is an explicit grade level standard...

Using Scoring Rubrics to Evaluate Inquiry
Sun, Apr 30, 2017 9:53 PM Decent article, not the best
Shows various weighs for different components. Does not appear to show how to write good descriptors for what is necessary to earn each particular level. Appears consistent with backwards design. Does not show good ways to translate a rubric to a grade.
