This level 4 Connected article provides an introduction to big data and the internet of things and how they are used to address air pollution in Christchurch.
The article explains how a research team used a variety of digital sensors to create a map of real-time air pollution levels across the city. People with respiratory disorders provided their GPS-tracked movements. City planners could use the data to clean up the most at-risk areas, and people with chronic obstructive pulmonary disease (COPD) could change their routes to reduce exposure. The article notes how other digital technologies can be used to make Christchurch (and other New Zealand cities) healthier and more sustainable.
Sensing data contains several infographics that will be useful for practising the science capability ‘Interpret representations’.
Check your school resource area for the article from the 2017 level 4 Connected journal ‘Where to next?’, download it as a Google slide presentation from Tāhūrangi or order it from the Ministry of Education.

The teacher support material (TSM) can be downloaded from Tāhūrangi (Word and PDF files available). The material highlights key ideas for the nature of science and the nature of technology. It contains two activities. The first involves the implications regarding the use of big data. The second uses Hub resources to investigate air pollution.

The most common form of air pollution is from particulates – small particles released from burning material. Scientists Dr Simon Kingham and Dr Peyman Zawar-Reza are researching the link between human health and the level of particulates. Learn more about this issue in the articles Air quality and Air pollution in Christchurch.
