I think what is needed here is to Keep It Simple.
I am new to darkroom work, but what I have discovered is that it is very *easy* to get passable results without worrying too much.
Read simple guide e.g. Ilford's.
Mix chemicals to standard dilutions.
get the temperature about right.
Follow the instructions using each chemical in the correct order.
Unless you do something very silly, you will get an image.
Once you have emphasized how easy it is to process your own film, you can then go on to say how interesting and challenging it is to improve your skill and understanding of the processes. It would be very easy to get bogged down in technical detail that will just put people off.
Mike, I will just discuss 'one shot', as I don't have that much time, so have to do all in about 2hrs. One of my goals too, is to show them that developing is not that difficult. I mean, getting a result can be done with a TMAX 400 and 70 seconds in Eukobrom 1:4 if you know what I mean.
And of course, getting a 'good' result is extremely difficult and so relative. Probably hours and hours to talk about, but I just want them to get started and also encourage them to go out there and read books, visit apug.org for answers etc. But if I overwhelm them with lots of theoretical stuff, they might think it is too difficult to do themselves.
And yes, temp is discussed, but I don't thinks I understand the last part you wrote: "depending on where the temperature basis is started at. ". You mean, if you develop on 20c that after a certain amount of developing time the temp will drop?
Exactly! Keep it simple. First stick with the 'normal' development procedures like shooting boxspeed, following the instruction manuals and understanding them too. Some of them already have troubles when they read something like 1:19 to mix a stopbath.

Continuing with keeping it simple, something like HC-110 or any other general purpose developer would be good to use, rather than more exotic, specialized, or home made chemistry.

True, HC-110 is very economical. The concentrate also lasts a long time, and the developer itself is very flexible.
echo 'The classic MQ developers like D-76 and ID-11 are also cheap, easy to prepare and use, and give good results with almost all emulsions.\
However HC-110 is an equally valid choice IMO.' >/dev/null

You could look up massive development chart.
It's probably a mistake to ask such a question on a site like this, as you can be quickly led down the road of complete confusion. As some others have said you need to keep it simple. I think what you have put in your original post is fine, but you may emphasise that development in general is all about time/temperature.

I think this is important, to keep it simple.

It's the combination of targeting a certain quality in the negative (to print or scan well according to whatever printing process is used), in combination with exposure, that is difficult. But film developing, on its own, is actually very simple, which works beneficially in this case.
The list mentioned in the original post is fine in order to explain the basic steps. By keeping things simple you also leave a 'buffer' of your own knowledge in order to answer the inevitable complicated question, perhaps from someone that has taken a darkroom class before, or something along those lines.
As an aside: visual tools help immensely, and I would recommend showing pictures of over-developed, under-developed, and normal negatives. In order for the audience to understand and relate to those results, it also makes sense to show resulting prints of such negatives, so that the audience can get a real feel for what happens when you start to push the boundaries of what's possible with film.
