 Given the structure of the AoS, it could be used for educational purposes. For high school students, lessons 1 and 2 could be used as a project with the aim of finding questions that ocean observations, such as Argo,  may help to understand, and how.  For students with a technical or science curriculum, that includes programming in python, other projects could be to find the seasonal change in temperature at the surface at a given ocean, and compare it with the changes at 1000 m or 2000 m, or explain - sometimes is very hard- the trajectory of a given float.  Teachers are welcome to open an [issue on the public github repository](https://github.com/euroargodev/argoonlineschool/issues) to get help in how to develop more projects.
