Automate a Water-Monitoring Network
Large automated systems coordinate many inputs, processes, outputs, and people. Reliability depends on validation, communication, security, maintenance, and safe responses when components fail.

STEM Automation and Impact
For students
Notice, predict, explain
Choose one part of the model. Predict how it connects to another part, then use the lesson evidence to explain your thinking.
For teachers
Pause for science talk
Show the model before the explanation. Ask “What do you notice?” and “What might change?” Then revisit student ideas after the worked example.
The big idea
Automation expands reach but does not remove responsibility
A responsible automated system makes its purpose, data sources, decision rules, uncertainty, human oversight, and social and environmental impacts visible.
Work it through
Plan a watershed alert network
- Step 1 Map sensor stations that measure conditions such as temperature, turbidity, water level, and conductivity at different locations.
- Step 2 Plan code that validates readings, compares trends with thresholds, stores evidence, and sends tiered alerts.
- Step 3 Include calibration checks, missing-data handling, manual confirmation, and a safe response when a sensor or connection fails.
- Step 4 Assess who benefits, who maintains the network, how communities participate in decisions, and how automated warnings could be misunderstood.
