# Assessment Instructions: Problem Set 04 - Solar System Reasoning

## Inputs to Inspect

- Student submission
- `problem-set-04.html`
- `problem-set-04-solutions.html`
- `../syllabus.html`
- Relevant lecture slides and notes

## Grading Standard

Grade concrete reasoning, not just final answers. Require units, assumptions, evidence interpretation, and clear prose. For quantitative problems, identify whether errors are setup errors, unit errors, arithmetic slips, or interpretation errors.

## Problem-Specific Emphasis

This assignment covers Lectures 07-08. Feedback should explicitly connect each error to the corresponding lecture objective and to the physical model or observational evidence being practiced.

## Resubmission

Students may revise eligible work to improve mastery and grade. Feedback should identify the next reasoning step without simply replacing the student's work with the solution key.
