This packet is everything a parent or guide needs to assess Unit 05 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 collecting weather-station data and tracking a front through it.
By the end of the Atmosphere & Weather unit, a student should be able to:
Six criteria, each judged Not yet / Approaching / Mastered (Page 3).
Log station data over time; track a front through the trends.
The student reads the instruments into a forecast (Page 4).
Readings, the trend, and the forecast 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 read the instruments and justify the forecast behind them. 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 |
|---|---|---|
| Structure & air masses | ||
| Troposphere | lowest layer | Where nearly all weather happens; temperature falls with height |
| Air mass | body of air | Takes on the temperature and humidity of its source region |
| Front | air-mass boundary | Cold, warm, or occluded — where weather changes, not a place |
| Pressure, humidity & change | ||
| Air pressure | barometric pressure | Falling pressure often signals an approaching front or storm |
| Humidity | water-vapor content | Relative humidity vs. dew point; not the same as temperature |
| Dew point | saturation temperature | The temperature at which air saturates and clouds or dew form |
| Weather vs. climate | today vs. decades | Weather is a moment; climate is the long-run pattern |
| Precipitation | rain, snow, sleet | Water falling from clouds — a weather output, not the whole cycle |
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Atmospheric structure | Cannot name the layers or thinks the air is uniform top to bottom. | Names the troposphere and above but cannot say what changes with height. | Describes how temperature, pressure, and composition change through the layers and where weather happens. |
| Air masses & fronts | Sees weather as random, unconnected to moving air. | Names the front types but cannot predict what each one brings. | Predicts the temperature, cloud, and precipitation changes as a cold, warm, or occluded front passes. |
| Pressure, humidity & clouds | Confuses temperature with pressure or humidity. | Reads each variable alone but cannot combine them. | Relates pressure, temperature, and humidity to cloud formation and reads the dew point off the data. |
| Weather vs. climate | Thinks weather and climate are the same thing. | States the difference but applies it inconsistently. | Distinguishes a weather event from a climate pattern and explains what each time-scale can and cannot tell you. |
| Lab technique (weather-station data & front tracking) | Records instrument readings carelessly or not at all. | Logs the data but cannot track a front through it. | Collects station data over time and tracks a front's approach and passage from the trends. |
| 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 reading the trend: not just logging numbers, but seeing the front in them. Ask “what is the pressure doing over time, and what does that tell you is coming?”
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.
