[Callers] Concerns calling for total beginners in highschool

So, i hope this is being sent to the appropriate network. I was asked recently to call a contra dance for a highschool class of about 30-40 students. I would like to reach out for advice on working with not only youth, but total groups of non-dancers. in my experience, youth picks up rather quickly, but the last time i worked with a summer camp i spent waaay to much time instructing, so i wanted to see if i could get some pointers. any dance selections that you folks have found particularly friendly? the dance will only be one hour and i was asked to do contra dances. i am, at this point, planning on circle dances or mixers and a whole set dance like VA Reel; though, i would like to do a contra. dog branch reel or a dance where there is little or no crossing the set and pleanty of forgiving moments should there be confusion (which obviously should be mediated in the walkthru/lesson). so, that is where i am. any suggestions or advice would be greatly appreciate. peace.
