Darkroom technique- two negatives?

Question:Ok, so in my photo class, I've got a pretty tough surrealism assignment. I've got to use some of these techniques: doubles exposures, multiple exposures, solarization, rayographs, dodging, and burning. Unfortunately, my photo teacher is kind of flaky and won't teach us how to do these. Does anyone have clear instructions on how to do these?

Also, I've been working on sandwiching two negatives in the carrier, but the way I want to put them together, they don't overlap completely (but one half of the photo ends twice as dark as the other). Do I have to completely overlap the two to make it work or is there a way to fix this?

You could expose one negative for 1/2 the time, take it out put in the next one expose that one to get a double. I used to that but its been a few years. To solarize you can expose the photo normally put it in the developer for half the time and then expose it to light for a few seconds and continue developing, if you do this by turning on the lights in the darkroom, check with anyone else in the darkroom that you are not going to expose any of their materials because that would not be cool.
What is your teacher getting paid for if he/she isn't teaching you the things you want to learn? I hope you 're not paying for this class or I'd be pissed.
You can find books at the library or any good sized bookstore(Barnes & Noble definitely) or a camera store on alternative processing, Photo-imaging by Jill Enfield is a good one, I'm sure you can search the web for step by step tutorials as well, since your teacher can't be bothered.
