Little suggenstion- Never remind the nose when teaching. Talking about certain kind of problems (of course I do not mean DCS!!!) may create them where they never would have been created before.
Let me give you a simulation of such a lecture on breathing:
(somewhat reminding of my own in my course, and of me sitting as evaluator in the crowd during later days):
Sitting on the table in front of the class, looking in the eyes all of my odience (3 more IC students and 3 ITs, dont ask why so many ITs!!!!) one by one: "Now we'r going to talk about breathing (Dramatic pouse, going with the eyes drill again). Breathing is one of our basic tasks in life, one we alwais do without even paying attention to it. However, when we dive, we may well pay attention to every breath we take." (now remeber- you must make the lecture interesting, and make the audience participate in it to get higher score, and make them not get bored / crucify you later) little pause (no eye drill this time) "Any idea why?" (looking for one who wants to talk. now, remeber- your friends that do the course with you, will ask you easy, some times even dumb question, to make you look good, while the IT may ask you either very tough question to check your knowlege or EXTREMELY DUMB question, to see how you cope with a darvinist, or simply to make you lough so hard you can't remeber what you were about to say). choosing a friend, the genious goes "Becouse we are now in a new enviorment we are not used to" choosing the other clever participant of the course "Yeah, and we also breath through special equipment, and the sensation is different" (now how the hell did this guy know the sensation is different if it's the first time he hears about it?!?!?! he's really smart eh???). Now the IT looks like he really likes to ask you a question, and wanting to get a good grade you let him ask it "But Isn't it really scary breathing underwater?!?!?!? and what if the regulator slides out of your mouth???" seeing his sencire face you can't help but break out loughing. you start: "Dont worry, we will learn about that later (seeing his horrified face, a definite darvinist this one!!!!) really, dont worry it's my next topic (he seems relaxed now). " Going on "Right you two, that's true. We're in a new eviorment. It is a bit unnatural, for us humans, land creatures to breath underwater. As you also mentioned, breathing through the regulators feels a bit different than breathing in air. What we have to remeber though, is quite simple" (a dramatic pause, with the looking in the eye drill) "REmeber this rule, as it is one of divng's most important- ALWAIS BREATH!!!! never stop breathing! breath regularly- fill your lungs and than empty them. You must also learn to count on your regulator- It will not fail you (now you can see the darvinist thinking about giving you the obviouse dumb questin, but this time he let's it go), it will deliver you as much air as you need- as much you demand. This by the way, is why this regulator is called a "Demand regulator"." now- another factor in the score, is giving the audience some reall background you have regarding this, like dives you had and such. So you try to come up with something in this aspect too: "I want to share with you a story. When I was a kid I used to have dreams about the see at nights. I had a motive that repeated in many of my dreams: me swiming underwater, for some time, untill I feel I need to go up to take air, only for some reason I can't. Than after some time I take a breath- and what a wonder!!! I can breath!!!. Years later, when I turned 16 and had my OW course, I found out that this wonder can be achieved!!! It is one of the reason I am so hooked on the subject." Now that you'v gone all through the subject, and through all the aspects of a good lecture, you need just to sum it up:
"What we'v discussed now is breathing- what is different in breathing underwater?, what is the most important thing to remeber regarding breathing? I want to hear you guys say it!!! yes, now- (they shout) "NEVER STOP BREATHING!!! very good-once again, this is very important, say it louder- "NEVER STOP BREATHING!!!! very good guys. never you stop breath when you go with scuba gear. I see you later in the pool, say in half an hour after we all eat?"
REmeber- every lecture must start with an introduction, followded by the body of the lecture, in which you need to let the audience participate, and tell some nice storys from your history. Finish by summing it all up and going over the topics. If you tought something that is a basic rule of scuba (such as equalizing, alwais breathing and other such issues) repeat it dramaticaly (and I also recomend making THEM say it). Also remeber to conect things you talk about to things that were talked about before or where felt/used/practiced earlier in the pool.
Taht's about it, hope I helped you. Any more help you need in your course, I will be happy to help
On reall courses I teach I also talk a bit about the importance of breathing for keeping good bouyancy, but in you own IC dont do it, try to stay within the subject. As for the exact way of how to breath, I'm sure you can come out with something good here, But I think I gave the most importent issues and aspects of a lecture here. Expect questions such as "But when we equalize we stop breathing for a moment" from the IT, and try to preplan answers to questions you think are very liked to be asked. (Actualy you can divert the audience to ask question you want them to ask but taking in certain ways, a method I like to use when teaching).
P.S-
If my writing is a bit blur- just remeber I didn't do it in english, rather in hebrew).
