Activity objective

Match symbolic soil cards to water-path clues and explain how runoff, pooling, and plant signals change the classroom model.

Teacher guidance

Ask what the system needs to keep working.
Compare short-term yield with long-term health.
Make system loops sequential and label each resource flow.

Evidence checklist 0/5

Prediction made before changing the water path.

Web demo playusable

garden-water renders as a environment toy model with adjustable controls, a checklist, and public safety copy.

Keep rendered route, console, network, and safe-copy checks attached before release embedding.

Native mobile screencontract ready

The surface uses touch-sized controls, a single-column mobile layout, no hover-only actions, and no raw child media capture.

Port the same controls into the native shell and verify phone, tablet, offline resume, reduced motion, and bottom-rail navigation.

ChromeOS input paritycontract ready

The web surface keeps range controls, stepper buttons, evidence capture, and review links available to keyboard, pointer, and touch users.

Capture Chromebook-class keyboard, pointer, touch, reduced-motion, and timing proof before widening classroom rollout.

Public copy and safety

Keep the activity local-first, age-appropriate, and behind teacher review before public sharing.
No crop result guarantee, farm operation, pesticide advice, animal-care guidance, environmental-control instruction, water-rights advice, regulatory advice, or real irrigation plan.
No raw device data, child media, or biometric input.
