I definitely recommend including some case studies related to AI for social good, as well as ethical issues related to AI, since I think both of these can be particularly engaging. You might also want to have students do their own projects where they research a particular AI application or AI ethical issue.
Some existing resources to check out are:
AI4ALL: read here and here (formerly SAILORS), which runs 1-3 week programs for high school students (primarily girls and other underrepresented minorities). I’ve seen some of these high school students present their work and it was awesome.
Curiosity Machine AI Challenge this is geared towards somewhat younger kids, but might be helpful to look at
Calling Bullshit: Data Reasoning in a Digital World If most of your students don’t know how to code, it might be useful to incorporate some data literacy skills (which I think it’s increasingly important for everyone to have) of the kind listed here.
