Explanation of the grid. How it was developed and why., e. g. voluntary work versus influencing policies versus education versus making. How to place a CS activity. Obvious differences in potential (ethical) guidelines depending on where activity is placed. „Look & feel“ of the Grid. Learning how to apply it to become aware of potential caveats and ethical issues will help to organise citizen science activities in a way that creates a better cost-benefit-ratio and that systematically takes ethical issues and other challenges into account. Who is it aimed at? Anybody who is interested in CS: Scholars, practitioners, policy makers. Political scientists are welcome, too! What will you learn? Awareness what consequences it can have, if a heavily loaded term like CS is used without differentiation between the multitude of meanings. Learning how to apply it to become aware of potential caveats and ethical issues will help to organise citizen science activities in a way that creates a better cost-benefit-ratio and that systematically takes ethical issues and other challenges into account.
