Go down to the shore of one of those lakes before dawn, preferably on a day when the water is still (and before dawn is usually when you’ll have the most luck with that anyway). Take a bag full of ice cubes and toss them in the water close to the shore while you try to photograph the splash, backlit by the slowly lightening horizon. Or you could dump them all in at once and photograph the flotilla with a little plastic toy polar bear on it.
Hmm. Maybe dip something that doesn't handle ice well, like a flower, in some water and throw it in the freezer? That might come out looking like crap, but who knows. Or maybe you could try suspending something in a block of ice? OORRR. Just crush some ice and put it somewhere artsy. Hope that helps, I'm no photography person. xD
