Review and synthesize the Earth systems unit, spheres, water distribution, watersheds, currents, the water cycle, California water, and conservation, into a connected summary.
This week ties together the whole Earth systems unit: the four spheres, the surprising 3 percent fresh water fact, watersheds carrying rain to shared outlets, ocean currents moving heat and nutrients, the sun-powered water cycle, California's engineered water system, and conservation design thinking. Each week built on the one before, and this review connects them into one bigger picture of how water and Earth's systems truly work together.
A good review is not just remembering facts; it is explaining connections. Can you explain how a mountain snowpack connects through the water cycle to a city's water supply, and why conserving that water actually matters? That kind of connected explanation is the real goal of this unit.
Mastery looks like: They can explain a connected chain across at least three Earth-systems unit topics, spheres, water cycle, watersheds, currents, California water, or conservation, without needing separate prompts for each.
Common stumbles: Treating each week's topic as an isolated fact rather than part of one connected system; struggling to explain why a connection matters, not just that it exists.
