Well, snakies, it's 2/3 of the way through the first month of term, and I make that about 1/4 of the way through term in total. Amazing how fast it goes! I just finished knitting Escargot, so the next step will be blocking that.
My suggestion to you this week is to give Tunisian Crochet a go. It fits into several classes - if you've never done it before, it's perfect for Flying or Muggle Studies. Because it looks sort of weird - some stitches look like knitting, some look like weaving - it would work for DADA. If you use worsted weight yarn, you could turn it in for COMC. I'm sure you can think of plenty more options just by using particular colours or making certain things from it (maybe a bag for your sneakoscope made in worsted weight yarn in the colours of an imaginary school, perfect for wearing to a soiree...).
Tunisian crochet is sort of like a cross between knitting and crochet. One row picks up stitches, like knitting, and the next casts them off, pulling loops through loops more like traditional crochet. Sneakily, it also uses masses of yarn. Rack up those yardage bonuses!
There are heaps of tutorials out there for Tunisian crochet. I found this one useful, and thought this one was very clear, with great pictures (man, I love blogs.) If videos are more your style, I liked this one to get started, and then there are lots linked in the sidebar.

A dishcloth would be perfect to give this new technique a try. Just chain as wide as you want it and then keep on going until it's sufficiently long. Or how about a little pouch? If you need a pattern, there are plenty available for free on Ravelry.
