Here's a wonderful one from which Vanesa sent me with the suggestion that it looks as if it might be interesting for class, though she hadn't yet used it or come up with a lesson plan.
It looks brilliant for class, Vanesa, if you ask me (thanks so much 😉 ) !
With this one, however, I'm not so sure we actually want the usual sort of lesson plan, with pre-watching and while-watching activities and a follow-up and so on. I wonder if we couldn't actually get our learners to film something of their own along the same lines — especially if you happen to have classes with a huge range of ages.
You'd want someone in your classes (and I'll bet you've got lots!) adept with filming on a smartphone or other device and perhaps willing to do a little editing for us; you'd want scriptwriters, too (that could be everyone in the class); and learners willing to be filmed (not necessarily all of them). You want to start exploiting — for its opportunities for language learning — all that technology your learners are carrying around with them!
Or why not do it as a project shared across different classes: start with your youngest group and then work upwards…?
They wouldn't necessarily have to upload it to YouTube: a shared Google Drive folder makes a great alternative if you — or they — don't want the rest of the world to have access to it. You could also just watch what they film directly on their phones, if privacy is going to be an issue (and it is!).
You do also have privacy options on YouTube itself.
