This project was much more than this: it was a genuine passion project in every sense of the word. Three of my students approached me with the idea of tracking CO2 to give schools a better idea of when there was pollution and which way it was going. I agreed to support them during allocated programming time, and to help them reach out to other schools.Ĭircuit design of the CO2 sensor using just Raspberry Pi, designed on circuito.io They had had some experience of using Raspberry Pi computers, and knew that it was possible to use them to make weather stations, and that the latest versions had wireless LAN capability that they could use. Flipped learning is a teaching approach in which some direct instruction, for example reading articles or watching specific videos, is done at home. This enables more class time to be used to answer questions, work through higher-order tasks, or do group work, and it creates more supervised coding time. I was able to offer students support with this project because I flip quite a lot of the theory in my class.

I initially started doing this because when I set coding challenges for homework, I often had students who confessed they spent all night trying to solve it, only for me to glance at the code and notice a missing colon or indentation issue. I began flipping the less difficult theory for students to do as homework, to create more programming time in class where we could resolve issues more quickly. This then evolved into a system where students could work much more at their own pace and eventually led to a point at which older students could, in effect, learn through their own projects, such as the pollution monitor. The students started by looking at existing weather station projects - for example, there is an excellent tutorial on the Raspberry Pi Foundation’s projects site. Students discovered that wind data is relatively easy to get over a larger area, but the key component would be something to measure CO2.
