Below is the rubric that we will use for grading each question on the project. There are two different kinds of rubrics on there - one is a quality of work rubric (out of 3) and the other is a level of understanding rubric (out of 3). Most questions I will probably choose to use one or the other on - for example their graphs I will use the quality of work rubric on whereas their written explanations I will use the level of understanding rubric on. There may be a few cases where I want to use both, in which case I will grade with both and then average the scores to still give a score out of 3.
I will hand out a copy of this rubric to the students with the project and I will also warn them that in general most written explanations (on activities etc) will be graded with the "level of understanding rubric".
