Use these targets, vocabulary, rubrics, examples, and score sheet with the instructor's approved lesson and procedure. This is an assessment companion, not a complete lesson or safety authorization.
Student lessons, data, and worked answers: Unit 01 learning pathway.
The student demonstrates the following:
Five science criteria plus separately reported integration (Page 3).
Use the supplied source, inputs and practice; this does not certify unobserved hands-on technique.
Instructor-selected new variant or observation, with approved references and accommodations.
Keep source/date, chosen level, calculations, uncertainty and practical/safety review.
You are making a decision, not adding up points. For each criterion, decide whether the work is Developing, Proficient, or Mastery — the column language tells you which. A criterion counts as mastered only when the student can both do the technique and justify the chemistry behind it. Each student has three tokens per term; each token retries one rubric criterion. Approved accommodations, equipment failures, and approved absences are handled separately and do not consume these tokens.
Accept listed synonyms; use the distinction column to resolve near-matches.
| Term | Accepted explanation | Distinction |
|---|---|---|
| Hydrogen bond | Intermolecular attraction | Not the polar covalent O–H bond within water. |
| Hydrolysis | Water-assisted bond cleavage | Reverse bookkeeping to simplified condensation. |
| Lipid | Fat, phospholipid, steroid family | Not one repeating-monomer polymer family. |
| Enzyme | Biological catalyst | Changes rate, not equilibrium or overall reaction ΔG. |
| Sample SD | s; spread among replicates | Use n−1 for sample variance; not SE. |
| Standard error | SE = s/√n | Mean uncertainty under independent sampling, not individual spread. |
| pH | −log10 hydrogen-ion activity | Concentration approximation gives 100-fold change from 7 to 5. |
| Control | Known positive/negative reference | A failed blank invalidates a simple sample interpretation. |
| Criterion | Developing | Proficient | Mastery |
|---|---|---|---|
| Macromolecule structure & function | Confuses building blocks or molecule families. | Matches families but needs help explaining linkages. | Links carbohydrate, lipid, protein and nucleic-acid structure to function; distinguishes polymers from lipids. |
| Enzyme behavior & factors | Treats all rate changes as the same mechanism. | Predicts a trend with reminders about controls. | Interprets enzyme rate data using pH, temperature, substrate and controls; reports replicate variation and limits. |
| Water & hydrogen bonding | Names a property without molecular cause. | Describes polarity with an incomplete mechanism. | Traces cohesion, polarity and heat capacity to hydrogen bonding and correctly interprets pH ratios. |
| Connecting chemistry to living systems | Lists molecules without a cell mechanism. | Connects one structure to a prompted function. | Explains how molecular interactions and energy barriers constrain cell function without changing equilibrium by catalysis. |
| Lab technique (food-test indicators) | Ignores controls or invents observations. | Interprets recorded controls with coaching. | Interprets positive/negative controls and limits; separately demonstrates any approved indicator technique required by the course contract. |
| Integration (cross-domain) | Makes no supported connection between the source and the science. | Uses the source but needs help connecting evidence, writing, or limitations to the science. | Independently connects History, Reading, and Writing using a cited source, appropriate evidence, a limitation, and a scientific explanation. |
Public, nonsecure calibration. Students attempt first; an instructor supplies a fresh variant or observation for assessment.
A new synthetic six-amino-acid linear chain is hydrolyzed completely, and an indicator run has a violet water blank as well as a violet unknown. How many links are broken, and may the unknown be called protein-positive?
Science criteria 1 and 4: structure-to-function diagrams; criterion 3: hydrogen-bond mechanism; criterion 5: controlled interpretation plus separately observed approved technique, not a worksheet-only practical pass.
Use the unit’s actual data and criterion-linked evidence. Require a new variant or observation for assessment; never infer hands-on technique from a supplied-data answer. Integration cannot reduce the science grade or block a practical pass.
All unit cases: student learning pathway. Record chosen level, task ID, source, first attempt and instructor follow-up.

Integration is reported separately and cannot lower the science grade or block a science demonstration pass. Science and practical criteria determine that pass.
