What concrete projects engage middle schoolers in nuanced digital citizenship?

[SavannahOL]

As a middle school technology teacher, I'm developing a new unit on digital citizenship for my students, but I'm finding most available resources are either too simplistic, focusing only on "don't cyberbully," or too abstract for 12-year-olds to connect to their daily online lives. I want to create engaging lessons that cover critical thinking about misinformation, understanding digital footprints, and ethical online behavior in gaming and social media, but I need concrete, relatable activities. For other educators, what specific projects, discussions, or digital tools have you used successfully to teach nuanced digital citizenship concepts? How do you facilitate meaningful conversations about topics like echo chambers or data privacy without causing anxiety, and how do you assess student understanding beyond a simple quiz?
