Although the calls for ethics in Computer Science (CS) education and efforts made to answer the calls have been longstanding [1], there exists fear and urgency particularly now in regards to the increasing threats made possible with AI [2]. Simulations have been shown to be effective for learning in a number of higher education disciplines [3] and this demo presents Rehearsals, a digital simulation tool for learning about the ACM Code of Ethics [4] in CS education. Rehearsals currently has one scenario based on Principle 1.7 Honor Confidentiality and will have a second scenario added based on Principle 1.6 Respect Privacy. Each scenario consists of a number of videos, with each video setting the scene for a multiple choice question requiring ethical consideration. Intelligent agent coaching is also included. We will demonstrate the two scenarios from the student point of view, as well as how to author a scenario from the educator point of view. The idea of Rehearsals was presented as a Lightning Talk at SIGCSE TS 2025 [5] and we look forward to sharing how it functions so far with the SIGCSE community. We will seek feedback through discussion and online survey, and also continue to extend invitations to join our community of practice at https://rehearsals.online.
