I think I will show slides day 1, great idea!
Yes, do it, it is unique and breathtaking! Especially for your young students who have never seen it.
But important, use quality gear. Some recommendations:
If you want a carousel projector, the best are the Leica Rt-m and Rt-s models (30% more brightness than the best Kodak carousel models).
Best lens: Super-Colorplan Pro
Kodak:
The later Ektalite and Ektapro models.
Best lens: Kodak Ektapro FF 2,5/93
Tray projectors:
Leica Pradovit PC / IR.
Best lens: Leica SuperColorplan P2 2,5 /90
Second best: Leica Colorplan P2 2,5/90

For projection screens I recommend the Da-Lite programme.
Slide projection is one very good reason for using slide film in photographic education.
The other is slide film as an excellent learning tool.
Reversal film, both color and BW, is by the way one of the best learning tools for photo students:
With reversal film in the camera you just have to do it right before pressing the shutter:
- composition has to be right
- exposure has to be right.
With a slide you create a finished image in the moment of the shutter click. No possibility of different framing or post-processing / "enhancing" afterwards (hybrid workflow excluded; looking only at the real slide on the lighttable and in projection).
With shooting slides you have to think before pressing the shutter, you have to be precise and you have to know what to do.
That is one of the strengths of this film type.
It is a strong "what you see is what you get" approach.
And that makes it one of the strongest and best learning tools in photography.
If you master reversal film, then you can master all: BW and Color negative, instant, digital.
I've followed one of the best current photography teachers / photo professors in this regard, H. Mante.
And can confirm his concept. I have the best experiences with teaching photography by using color and BW reversal film (not exclusively using slide film, but using it quite a lot in addition to negative film and printing).
I can highly recommend using slide film as a powerful learning tool.
