This lab report rubric focuses on a Claim Evidence Reasoning (CER) format. It is general enough to be used throughout the year. It is leveled for grading purposes, and goes with the lab report guidelines posted on here.
The leveled grading allows students to see what areas they may be lacking in. Truly challenging items, such as, providing reasoning to link evidence and claim, are put in level 3-4. This rubric allows success for students still struggling with higher level items. If a student receives all points in levels 1 and 2, they are at a 64/100.
I have found this is a huge improvement in having discussions with students and parents about how students can do better on lab reports!
