All that would do is scare a bunch of kids into thinking, "OMG, Grandpa's gonna croak, any minute now".
Themselves, they will continue to act and think as if they were indestructible. No high schooler walks around thinking about what's going to happen to him, someday in the distant future.
The only advice I would offer to kids on Death is the one John Cardinal Newman gave (paraphrasing):
"Don't be afraid that your life will end, be afraid that it will have no beginning."
Catholic teaching and iconography have a lot of references to death, beginning with Jesus dying on the Cross. So Catholics don't need no steenkin secular teachers to come along and tell them what Death's all about.
In fact, secular types would do their damndest to dispel the ideas of Heaven and Hell , instead pushing "you're really stupid to believe that religious nonsense". But hey, that's what secular types see as their mission, i.e., undermining religion.
