Although probably not a "must" I think a brief tutorial on sky navigation
R.A./Dec., degrees, arc minutes..., circumpolar/seasonal constellations,
finding the invisible with the visible, etc. is a good step to spark an
interest. The ability to solo starhop to a great attractor using a telrad
or other finder is easy to teach and makes a good accomplishment.
I'd be happy to drop off my 10" Dob for those weeks or longer--It's a very
tough Meade Starfinder with nothing automatic and it fits in the trunk of
most parent's cars. Call/email me directly if you're interested.

Subject: [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?
