The University of Texas has developed over one hundred videos, and a bunch of related teaching materials, for a course they share with anyone about ethics.
It’s called Ethics Unwrapped.

You can see what they offer in the screenshot at the top of this post.
You can read more about the program at this Science Daily article, Video-based ethics program increases moral awareness, study finds.
