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 05 learning pathway.
The student demonstrates the following:
Five science criteria plus separately reported integration (Page 3).
Use approved figures and supplied rates; no handling, heating, drying or sampling animals.
Check exchange mechanisms, normalization and limits (Page 4).
Observations, structures, and habitat reasoning kept distinct.
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 analyze the supplied evidence and explain the exchange mechanism and its limits. 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.
| Canonical answer | Accepted synonyms | Common confusion / discriminator |
|---|---|---|
| Fish groups & structures | ||
| Jawless fish | lampreys & hagfish | No jaws, no paired fins; a skeleton of cartilage |
| Cartilaginous fish | sharks, rays & skates | Cartilage skeleton; no swim bladder. Buoyancy and ventilation strategies vary |
| Bony fish | ray-finned and lobe-finned groups | Many, not all, have a swim bladder |
| Swim bladder | gas bladder | Gas-filled organ that controls buoyancy; only in bony fish |
| Onto land & amphibians | ||
| Gills | branchial respiration | Extract oxygen from water; not the same as lungs |
| Metamorphosis | larva-to-adult change | A gilled tadpole becomes an air-breathing adult |
| Amphibian | frog, salamander or caecilian group | Life cycles and exchange routes vary; do not assume every species has a free-living tadpole |
| Permeable skin | moist respiratory skin | Breathes and leaks — ties amphibians to water |
| Mass-specific oxygen rate | mg O2/(kg h) | Normalize amount by both hours and kg; retain temperature and medium |
| Criterion | Developing | Proficient | Mastery |
|---|---|---|---|
| Jawless, cartilaginous & bony fish | Treats all fish as one kind of animal. | Names the groups but places examples in the wrong one. | Sorts a lamprey, a shark, and a perch by jaw and skeleton and gives a defining trait for each grade. |
| Gills, fins & oxygen comparison | Confuses structures or compares uptake totals without denominators. | Explains exchange but needs help normalizing time, mass or route shares. | Explains exchange surfaces; independently calculates mg O2/(kg h) and route percentages, states body/medium temperatures and limits a fresh comparison. |
| The move onto land | Explains new structures by an individual's need. | Names a functional constraint but treats function as evolutionary evidence. | Connects support, water balance and gas exchange to terrestrial conditions while distinguishing present function from inherited population change. |
| Amphibian dual life & metamorphosis | Assumes all amphibians share one fishlike life cycle. | Describes a typical frog cycle but overlooks variation or skin exchange. | Explains a sourced amphibian life cycle and moist-skin exchange; recognizes that life stages and exchange routes vary among amphibians. |
| Lab technique (image & record analysis) | Invents observed structures or a performed procedure. | Uses a source figure but omits evidence mode or measurement context. | Independently annotates an approved image/model, distinguishes supplied records from observations and defends a new mass/time calculation without an animal procedure. |
| 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. |
The split between Proficient and Mastery is structure to function: naming a fin is not enough — the student says what it does for the animal. Ask “what problem does the swim bladder solve?”
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.
