My Science Teacher is a Wizard

Blake Drywater is plagued by bullies, doesn't like any of his classes, and hates school in general. However all of this changes when he learns that his new science teacher is a wizard. His class are promptly turned into roaches and earthworms, and are magically taken to England in the blink of an eye. But Blake soon learns there is more than science going on in his classroom. An evil wizard is after a potion his teacher has made--a potion with enough power to change the world. And when Blake is given the potion soon thereafter, he finds himself facing problems far harder than any science exam!
