  We describe lessons learned from using the air:bit project to introduce more
than 150 students in the Norwegian upper secondary school to computer
programming, engineering and environmental sciences. In the air:bit project,
students build and code a portable air quality sensor kits, and use their
air:bit to collect data to investigate patterns in air quality in their local
environment. When the project ended students had collected more than 400,000
measurements with their air:bit kits, and could describe local patterns in air
quality. Students participate in all parts of the project, from soldering
components and programming the sensors, to analyzing the air quality
measurements. We conducted a survey after the project and describe our lessons
learned from the project. The results show that the project successfully taught
the students fundamental concepts in computer programming, electronics, and the
scientific method. In addition, all the participating teachers reported that
their students had showed good learning outcomes.
