I have developed 7 debating topics where the students pretend to be members of government debating topics at the senate (the topics are realistic). The slides are fully editable that can be personalise to your setting.
The 2 teams are 'Ministers' (the government - they are proposing a new project or law) and the 'Shadow Ministers' (they are opposing the new project or law).
I have also included a Debating guide that explains each of the speaker's roles and some general debating rules. This is useful for both teachers and students.
