Documentaries allow the audience to learn the basics of a subject in an entertaining way. Set up a documentary night for residents, either socially-distanced in the same room, all together live on computers or TVs, or as a one-on-one. The topic can be voted on by residents if it's a group watching, or pick a relevant film for the time of year/ current events. Afterwards, ask residents to discuss what they most appreciated from the film. As a group activity, residents can discuss what they liked with each other!
For an easy pick, this is a documentary on YouTube about killer whales!
