Help with curling my straight hair?

I wanted to know If i could curl my shoulder length, layered hair. Its kind of thick and straight. And if i could how?? Also things that I can do so I could wear my hair curly or at least wavy to school. I know braids and scrunching are some things but do you think it would work for my type of hair? I have mouss and hairspray so please thats all. I also have a blow dryer and a hair curler but I only want to use that for parties, (probably for this weekend) And please describe. This is pretty much how my hair looks like

Try the Chi Hairspray it holds good. Do it from the inside out and start at the back. It looks like it will be pretty easy to curl since its not that long. good luck to ya.
