Where to dark room, wouldn't this take some money, and room?
Any room without windows would work fine, a spacious closet, a bathroom, etc. Bathroom works well because it has running water/drains and such. You could also talk to someone at your school about trying to set something up there.
Also the only particularly expensive thing about a darkroom would be an enlarger. Chemicals and paper will probably run you less than $50 and these need to be purchased new. If you can salvage an enlarger, definitely go that route. Ask around, parents, grandparents, aunts, uncles, school, church (if you're into that), just, as many old people that you know well. If you can't find anything that way, prowl around Craigslist or eBay for a while, I've seen whole darkroom sets (timer, enlarger, chemical trays) for less than $100. But half the fun of brown townog photography (for me) is trying to work with stuff that's old and half broken, so don't fret if you can't find stuff in tip top shape. As long as it plugs in and gives off light through an enlarging lens, you should be able to jerry-rig something with enough ingenuity.
