[AZ-Observing] astro advice needed

Looking for advice...
I have the new opportunity of including 6 weeks or so of astronomy into my
middle school classes in the fall.?? I'd like to include some observational
component along with the textbook material (after all, we live in Az right?).??
So two things... 1.)? In your experience, is there a topic you would consider a
"must cover" in my? few weeks of classes that may or may not be in the standard
textbook materials (for example: urban light pollution-- not at all mentioned
in the texts);? and,? 2.)? I have a 12.5" Orion dob with Dob Driver II that I
can no longer transport in my small car.? Although I've had many a great star
party with it over the years (in fact EVAC still had a picture of it in the
gallery last time I looked) I would love to parlay or trade it for one or two
small dobs (6") that the students could easily use and transport.? I have a
couple equatorial mounted units that require too much fiddling for their skill
level and attention span.? I would love it if even a co
uple students came away with a fascination for astronomy-- many of us can
remember a key experience when we were young that planted a seed-- for me it
was looking through a scope and seeing Saturn for the first time one cold
October night when we were out trick-or-treating in the neighborhood as kids.
Thanks for any input you may have!

Jimmy, that's amazing that you can boil water with something that size.
Does it use a concentration system to get that hot? I ask, because my
attempt to boil water with the Sun fell a few degrees short of the goal. To
see my DIY attempt at solar cooking, check out:

At least it worked out well for cooking hotdogs. :) And how about that
cool image showing the rays of light getting concentrated?
