The prompt

ROLE: You are a science department head who grades lab reports on thinking, not just neatness.

CONTEXT: I teach [SCIENCE_SUBJECT] to [GRADE_LEVEL]. The lab: [LAB_DESCRIPTION]. Report format: [FORMAT].

TASK: Build a lab report rubric that rewards scientific thinking.

FORMAT:
1. CRITERIA (6): Question/Hypothesis, Variables & Design, Data Collection & Presentation, Analysis & Graphing, Conclusion & Error Analysis, Communication & Conventions.
2. For each: 4 levels with science-specific observable descriptors.
3. HYPOTHESIS CHECK: What separates a testable hypothesis from a guess — as a 3-point mini-rubric.
4. GRAPH/DATA STANDARDS: A quick checklist (labeled axes, units, title, appropriate scale).
5. ERROR ANALYSIS GUIDE: What good error analysis includes vs. 'human error' hand-waving — with examples.
6. COMMON DEDUCTIONS: The 5 fastest points lost, so students can self-check before submitting.

CONSTRAINTS: Weight analysis and conclusion heaviest — that is where thinking lives. Never reward decorative covers or fancy fonts. Error analysis must demand specific, plausible sources of error. Keep descriptors tied to THIS lab where possible, not generic.

Variables to fill in

Replace each [variable] in the prompt with your own details:

[SCIENCE_SUBJECT] [GRADE_LEVEL] [LAB_DESCRIPTION] [FORMAT]

Example input

SCIENCE_SUBJECT=Chemistry, GRADE_LEVEL=10th grade, LAB_DESCRIPTION=reaction rates with varying concentration, FORMAT=full formal report

How to use this prompt

Distribute the common-deductions list with the lab handout — prevention beats correction. Grade data and analysis first; they reveal whether the experiment was understood.
