I don't have any materials made yet because I won't be teaching this lesson for 2-3 weeks, but just looking at the key expression "Is it possible _______?", I think a choose-your-own-adventure game would be fun.
I would give the kids mini whiteboards in pairs or groups, and we'd go through the PPT game and in each scenario, I'd ask them "Is it possible to XYZ?" They would choose an option and vote with their whiteboards, and the majority rules. Something like that anyway!
I'm attaching an "Is it possible?" choose-your-own-adventure PPT that was made by another user. (I can't find the thread where it was originally posted, but I downloaded it a few months ago. Thank you to the creator!)
Hope this sparks some ideas for you! Good luck!
