Learners use simple wearable sensors to measure the air pollution they’re exposed to during everyday activities. They learn what air pollution is, where it comes from, and how it affects health. After collecting data on their journeys and at home, they explore maps and graphs to spot pollution hotspots and discuss easy ways to reduce their exposure.

Learners explore their local area by predicting where air pollution might be highest, then compare their guesses with real PM2.5 data collected in Part 1. Using maps, discussions, and simple visual tools, they discover pollution hotspots, understand why they occur, and think about ways to reduce exposure in their community.
Learners work together to decide the best place to install a wind turbine on their school grounds. By exploring renewable vs non‑renewable energy, collecting real measurements, and using both paper and digital maps, they investigate environmental impacts and justify their final choice. A hands‑on activity that builds decision‑making, mapping skills, and awareness of sustainable energy.
