Smart systems and climate change
Answers are for parents and teachers.
1
Copy the pattern for air pollution: cause, sensor, AI, machine.
Cause: exhaust, factories, burning rubbish. Sensor: measures harmful gases. AI: marks the worst streets. Machine or notice: warns people.
2
Explain how a smart system can save water on a farm.
Soil sensors measure moisture, AI decides if water is needed, and a machine waters only then.
3
Write one strength and one limit of a rain-warning system for a village.
Strength: an early warning. Limit: a broken sensor may give a wrong warning and needs upkeep.
4
Why do we say that some uses of smart systems are still ideas?
Some are only being tried or planned, so they need testing before people rely on them.
5
Design your own idea for one problem in four lines: problem, sensor, AI decision, action.
Any idea that follows the pattern and mentions a human check is correct.
