Abstract. We present a laboratory technique that can be used to measure tropospheric ozone, following a traditional method developed by Christian Friedrich Schönbein in the 19th century. The practice is described with two levels of complexity (the advanced level includes the production in the lab of paper strips as they were produced in the 19th century while the basic level does not) and is suitable for use by both high-school and first-year undergraduate students. The overall aim is to familiarise students with both the scientific methods involved and the related concepts of pollution and ozone. This technique was developed and presented in high schools during a communication campaign to celebrate the annual Galician Scientist Day and based on the detected need for a better understanding of the problems of climate change and pollution.

Short summary
In this paper, we present a practical approach to atmospherical sciences and air pollution based on project-based learning as a methodological foundation. For this goal, we visited 10 secondary schools where we presented the activity and introduce a laboratory practice based on the method of measuring tropospheric ozone with strips that reacts with ozone and turn in a certain grade of blue. We analyze the advantage of this practice through surveys.
