This packet is everything a parent or guide needs to assess Unit 07 at home — learning targets, the answers that count as correct, the mastery rubric, calibration examples, and a clipboard score sheet. No multiple-choice test: the student shows mastery by sampling soil and land use across plots and reading how the land is being changed.
By the end of the Land, Agriculture & Waste unit, a student should be able to:
Six criteria, each judged Not yet / Approaching / Mastered (Page 3).
Sample soil horizons; compare plots under different management.
The student reads a soil profile as a record of land use (Page 4).
Sample sites, horizon readings, and conclusions kept distinct.
You are making a decision, not adding up points. For each criterion, decide whether the work is Not yet, Approaching, or Mastered — the column language tells you which. A criterion counts as mastered only when the student can both sample the ground and defend a claim about how it is used and changing. A student carries three tokens per term; one token buys a re-do of one criterion on another day, so a single bad afternoon never sinks the unit.
Accept any answer in the synonyms column — they are pre-approved as equivalent. The third column flags the confusions that look close but are not yet, so you can coach precisely.
| Canonical answer | Accepted synonyms | Common confusion / discriminator |
|---|---|---|
| Soil & farming | ||
| Soil horizon | soil layer (A, B, C) | A layer in the profile; reads as a record of formation |
| Weathering | rock breakdown | Breaks parent rock into mineral soil over time |
| Industrial agriculture | conventional / monoculture farming | High yield, high input; contrast with sustainable practice |
| Sustainable agriculture | regenerative farming | Protects soil health; trades some yield for durability |
| Land loss & waste | ||
| Deforestation | forest clearing | Removing forest cover; distinct from desertification’s drying |
| Desertification | land degradation to desert | Fertile land turning arid; often follows overuse |
| Waste hierarchy | reduce–reuse–recycle order | Ranks options; reduction beats disposal |
| Landfill vs incineration | burial vs burning | Two disposal routes with different cost and impact |
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Soil formation & horizons | Treats soil as inert dirt with no structure. | Names soil horizons but not how they form. | Explains how soil forms from weathering and organic matter and reads its horizons as a record of that process. |
| Industrial vs sustainable agriculture | Cannot contrast farming methods. | Lists practices but cannot weigh their trade-offs. | Compares industrial and sustainable agriculture on yield, soil health, and inputs, and defends the trade-offs. |
| Deforestation & desertification | Confuses the two or their causes. | Defines each but cannot link cause to consequence. | Explains how deforestation and desertification arise from land use and what they cost soil, water, and biodiversity. |
| The waste hierarchy & disposal | Treats all disposal as the same. | Recites reduce–reuse–recycle but ranks disposal options loosely. | Orders the waste hierarchy and compares landfills, incineration, and recycling on cost and impact. |
| Field technique (soil & land-use sampling) | Samples carelessly or without a plan. | Collects soil or land-use data but records it inconsistently. | Samples soil and land use systematically and reads the data as evidence of how the land is being changed. |
| Integration (cross-domain) | Treats the science as isolated facts; makes no cross-domain connection. | Names a link to history, reading, or writing but cannot defend why it matters. | Connects the unit to its anchor across History · Reading · Writing (plus chosen electives) and defends why the connection matters. |
The split between Approaching and Mastered is the sample tells a story: a horizon reading isn’t mastery until it names how the land is being used. Ask “what does this soil profile say about how this plot is farmed?”
Read these before you grade. They show what Mastered and Not yet actually sound like, plus the edge cases where you should coach rather than decide on the spot.
