Several candlesticks stand lit behind McGonagall's desk.

They learn how to turn a match into a needle, beetles to buttons, a mouse into a snuffbox, an animal into a water goblet, a statue into a dragon, a statue into a bird, a statue into a rabbit, a book into a mouse, white rabbits into slippers, a teapot into a tortoise, a hedgehog into a pincushion, a rock into a Labrador, guinea fowl into guinea pigs, an owl into a pair of opera glasses, etc. The students also practise Switching Spells, Vanishing Spells (on vertebrates and invertebrates), and Conjuring Spells.

Behind the scenes

 * In the first two film adaptations, the classroom 1B is actually the Chapter House of Durham Cathedral
 * In film adaptation of Harry Potter and the Half-Blood Prince, a different set was used to portray this classroom. But in the video game adaption it resumes its layout from the first and second film and the fifth video game.T2.JPG
