This is a collection of authentic open data exercises suitable for high school students to become familiar with programming and data processing. Interactive Jupyter Notebooks are used as the learning environment for the exercises, where, for example, open data can be read, processed, and visualized using Python programming. No previous experience with notebooks or Python is required to use the material. The material is being developed as part of the Helsinki Institute of Physics’ project Education and Open Data and is made possible by the Finnish National Agency for Education state grant for the promotion of science education.
