Detailed Grading Criteria
Conceptual Mastery & Synthesis
25%“The Physics”Evaluates the transition from theoretical knowledge to specific application. Measures how effectively the student selects appropriate physics principles, derives necessary models, and synthesizes findings to explain the underlying physical mechanics of the observed phenomena.
Key Indicators
- •Identifies and justifies relevant physical principles governing the phenomenon
- •Derives appropriate mathematical models directly from fundamental laws
- •Synthesizes theoretical concepts with observed data to explain results
- •Articulates the underlying physical mechanisms driving the system
- •Evaluates the validity and limitations of the applied theoretical model
Grading Guidance
To progress from Level 1 to Level 2, the student must shift from merely defining general physics terms to selecting specific formulas or principles relevant to the project. While Level 1 work often resembles a glossary of unrelated definitions, Level 2 demonstrates an attempt to apply a specific equation to the problem, even if the derivation is missing or the application is clumsy. The transition to Level 3 (Competence) occurs when the student correctly identifies the governing physical laws (e.g., distinguishing when to use Conservation of Energy versus Kinematics) and accurately adapts the mathematical model to the specific scenario, rather than simply quoting a generic textbook formula. Moving from Level 3 to Level 4 requires bridging the gap between abstract calculation and physical intuition. A Level 4 student does not just solve the equation; they synthesize the mathematical derivation with their findings to explain specifically *how* the physical mechanism works, explicitly connecting the theoretical variables to the observed behavior. Finally, to reach Level 5, the student must demonstrate sophisticated synthesis by critically evaluating the limits of their model. They distinguish themselves by rigorously justifying assumptions, explaining deviations between theory and reality through specific physical factors (such as non-conservative forces), and demonstrating a cohesive grasp of how the system's variables interact beyond simple proportionality.
Proficiency Levels

Grading Guidance
Moving from Level 1 to Level 2 requires the transition from a vague narrative to a structured attempt at a procedure. While Level 1 work is often a disorganized list of equipment or a summary of an outcome without a clear process, Level 2 work identifies the primary variables and outlines a sequence of steps, though it may lack reproducibility or fail to control extraneous variables. To cross the threshold into Level 3 (Competence), the design must be functionally valid; the student must successfully isolate the relationship between variables by keeping controls constant, and the written procedure must be sufficiently detailed that a peer could reproduce the experiment without guessing.
Proficiency Levels

Novice
The design is fragmentary or incoherent, failing to establish a logical procedure to answer the research question.
Is the design incoherent or fundamentally misaligned with the research question?
- •Fails to clearly distinguish between variables (IV/DV are confused or missing).
- •No attempt made to control extraneous variables.
- •Procedure is missing, incoherent, or dangerous.
- •Design does not logically address the stated aim or hypothesis.
Quantitative Analysis & Evidence
35%“The Proof”CriticalEvaluates the integrity of data treatment and error analysis. Measures the execution of mathematical operations, statistical significance, propagation of uncertainty, and the logical derivation of conclusions directly from the calculated data.
Key Indicators
- •Performs mathematical operations and unit conversions with consistent precision.
- •Propagates measurement uncertainties to establish quantitative confidence limits.
- •Visualizes data relationships using appropriate scaling, error bars, and curve fitting.
- •Evaluates the impact of systematic and random errors on valid data ranges.
- •Formulates conclusions that strictly adhere to the limits of the calculated evidence.
Grading Guidance
To advance from Level 1 to Level 2, the student must move beyond merely listing raw data to attempting basic processing, such as averaging trials or plotting points, even if calculations contain arithmetic errors or lack units. The transition to Level 3 requires competence in execution; calculations must be largely correct with consistent unit usage, and the report must include a basic comparison between experimental results and theoretical values (e.g., percent error), ensuring the math supports the basic trend observed. Moving from Level 3 to Level 4 involves a leap in rigor regarding error analysis. While Level 3 relies on simple comparisons, Level 4 actively propagates uncertainty through calculations or utilizes error bars on graphs to visualize the reliability of the data. Finally, to reach Level 5, the analysis must be distinguished by a nuanced synthesis of statistical evidence; the student not only calculates complex uncertainties correctly but also explicitly uses these confidence intervals to validate or reject the hypothesis, distinguishing between random and systematic errors with high precision.

- •Visual representations (graphs/tables) include necessary precision elements (e.g., error bars, trendlines)
- •Identifies outliers or anomalies and treats them mathematically (rather than ignoring them)
↑ Unlike Level 3, the work includes quantitative propagation of uncertainty or statistical variation, rather than just simple percentage error comparisons.

Does the work attempt data processing, even if the execution contains errors or lacks quantitative rigor?
- •Contains noticeable calculation errors or misuse of formulas
- •Inconsistent application of units or significant figures
- •Error analysis is present but purely qualitative (e.g., describing sources of error without calculating their impact)
- •Gaps exist between the data presented and the conclusions drawn
↑ Unlike Level 1, there is an attempt to transform raw data into processed data (averages, rates, etc.) rather than just presenting raw observations.
Novice

Is the quantitative analysis missing, incoherent, or fundamentally flawed?
- •Presents only raw data without necessary processing (e.g., no averages or rates calculated)
- •Uses incorrect formulas for the task
- •Conclusions contradict the quantitative evidence provided
- •Omits mandatory elements like units or data tables
Technical Communication & Conventions
20%“The Report”Evaluates adherence to scientific writing standards and visual clarity. Focuses on objective tone, precise terminology, structural organization, citation mechanics, and the formatting of visual aids (tables/graphs) for readability.
Key Indicators
- •Employs precise physical terminology and SI units consistently throughout the analysis.
- •Organizes content into standard sections (e.g., Abstract, Methods, Data) to facilitate navigation.
- •Maintains an objective, third-person scientific tone free of colloquialisms.
- •Formats visual aids with correct axes labels, units, captions, and uncertainty representations.
- •Integrates citations and references according to required style guidelines.
Grading Guidance
Moving from Level 1 to Level 2 requires shifting from a casual narrative to a recognizable report structure; while a Level 1 submission often resembles a diary entry with informal language, a Level 2 report attempts to categorize information into distinct headers, even if the tone remains inconsistent or terminology is frequently misused. The transition to Level 3 is marked by the successful adoption of scientific conventions. At this stage, the student correctly uses SI units and standard physics vocabulary rather than lay terms, and visual aids transition from generic illustrations to functional data representations with labeled axes, ensuring the report is readable and technically functional. To reach Level 4, the work must demonstrate precision and seamless integration. Unlike Level 3, where components are correct but may feel disjointed, Level 4 writing features smooth transitions, mechanically perfect citations, and graphs that specifically highlight trends (e.g., proper scaling and error bars) to support the argument. Finally, Level 5 work is distinguished by professional polish and economy of language. The report eliminates redundancy, the abstract serves as a standalone summary, and visual aids are publication-ready, making the document indistinguishable from professional technical communication.

How to Use This Rubric
This grading guide targets the specific demands of scientific inquiry, balancing the rigorous requirements of Quantitative Analysis & Evidence with the logical structure of Experimental Design & Validity. In physics, the ability to propagate uncertainty is just as critical as deriving the correct mathematical model, ensuring students understand the limits of their empirical data.
When determining proficiency levels, look beyond the final calculation to the student's justification in the Conceptual Mastery & Synthesis section. A student who selects the wrong formula but executes perfect math should be scored lower than one who derives the correct model but makes a minor arithmetic error, as the former indicates a gap in physical intuition.
