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 06 learning pathway.

Unit learning targets

The student demonstrates the following:

How this unit is assessed

Science evidence

Use the five science criteria and selected learning level.

Practical record

Label supplied data separately from actually observed, approved skills.

Fresh transfer

Use a changed dataset or assumption, not recitation of the answer key.

Integration

Report source-linked writing separately; it cannot block a science pass.

How to read a Bright Minds rubric

Judge each criterion Developing, Proficient or Mastery from its stated evidence. A supplied-data result does not certify an unobserved practical skill. 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.

Six Criteria — Developing / Proficient / Mastery
Rubric
v0.1 · Page 3 of 5
CriterionDevelopingProficientMastery
Air-breathing marine tetrapodsGroups all large marine animals as fish.Names groups but not their shared ancestry.Distinguishes marine reptiles, birds and mammals by traits; explains lungs and terrestrial ancestry.
Mammals, not fishUses shape alone for classification.Calls whales mammals without diagnostic evidence.Uses mammary glands, hair and other mammal traits; contrasts lungs with fish gills without ignoring convergence.
Diving adaptations (evidence only)Treats animal data as a human challenge.Names an adaptation without mechanism or limits.Explains oxygen stores, circulatory and pressure adaptations from sources; interprets supplied tracks without human imitation.
Thermoregulation, feeding & migrationTreats insulation as heat generation.Names blubber or feeding modes without context.Explains metabolic heat and insulation, baleen/toothed feeding and migration; calculates model cooling rates with limits.
Lab technique (adaptation-data analysis)Omits time, units or provenance.Plots records but overclaims population or physiology.Analyzes supplied cooling, depth and effort records; states detection/interpolation limits and separates analysis from observed practical work.
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.
Mastery evidence
Correct work, supported reasoning, units and limits; only actually observed approved skills enter the practical record.
Not yet demonstrated
A memorized value, missing denominator or invented observation is insufficient. Use the criterion language and record what evidence is missing.
Grading it at home

The split between Proficient and Mastery is measure and explain: reading the model carefully and tying the result to the animal’s biology. Ask “how does this adaptation help a lung-breather in the sea?”

Read these before you grade. They show what Mastery and Developing actually sound like, plus the edge cases where you should coach rather than decide on the spot.

Worked assessment anchor

Supported reasoning
The inert models cool at 0.7 and 0.4 degrees C/min; that is not a live-whale experiment. Rough-condition encounters halve, but detection could also halve. The supplied track averages 125 m under linear interpolation, not a safe human depth.

Limits and coaching

Evidence boundary
No breath-holding, diving, cold-exposure or marine-mammal imitation is authorized. Interpretation of animal records must never become a physiological challenge.

Transfer calibration

Two observers each report 12 encounters, one in 30 minutes and one in 90 minutes. Are their rates equal, and does either count prove population size?

No: 24 versus 8 encounters/hour. Neither establishes population size without comparable sampling, identities, coverage and detection.

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