Week 15 · Term Two · One inspectable valley
Find out why one side of a ridge gets the rain, follow the water through the cycle, chart a change honestly, decide who pays, and explain the whole chain without overselling it.
Monday finds the cloud base from temperature and dew point and explains the rain shadow. Tuesday follows the water cycle and shows the engine can move rain but not make it. Wednesday picks the chart that does not mislead. Thursday writes a fair rule for everyone the engine affects. Friday explains the chain of effects and its limits.
25 minutes
Atmosphere · Why the ridge gets the rain
Explain how air rising over a ridge cools to its dew point, forms cloud and rain, and leaves a dry rain shadow on the far side.
Make
A ridge cross-section
Weather handoff: The cross-section is filed. Tomorrow the engine tries to change where the rain falls.
25 minutes
Systems · The water cycle has a budget
Trace water through the water cycle and show that a system can move water from one place to another but cannot create it.
Make
A water-cycle budget
Weather handoff: The budget is filed. Tomorrow someone wants to put it on a poster.
25 minutes
Data visualization · Pick the honest chart
Choose a chart that fits the data, start bar charts at zero, and spot how a cut-off axis or the wrong chart type misleads.
Make
A before-and-after chart
Weather handoff: The chart is filed. Tomorrow the people who paid for the town's rain get a say.
25 minutes
Ethics · Who pays, and who decides
Identify everyone a human change to the environment affects, and design a rule that monitors the impact and limits the harm.
Make
A engine operating rule
Weather handoff: The rule is filed. Tomorrow you explain the whole chain to the valley.
30 minutes
Explanatory writing · The chain of effects
Write an explanation that follows cause and effect in order, uses this week's evidence, and states what it cannot prove.
Make
A Systems impact diagram
Weather handoff: The impact diagram is filed. The valley has a model it can check, not a promise about the weather.
The diagram uses only work entered here. It is a family record of this week’s work, not a grade, an attendance record, or proof of mastery.
