Teachers are experts at making the most of slim resources. A paper bag, some bath tissue, a few markers, and a little imagination, and they can sweep students on a journey between the stars or diving down through the deepest, darkest depths of the sea. Like modern-day alchemy, the process of turning trash into treasure is called upcycling... and there is a whole lot more to it than simply saving a buck.
Here in New England, we're cold. Really cold. We've had about a week of sub-zero temperatures, cold enough for school to be delayed opening, cold enough for ski areas to be far less populated than usual on school holiday, cold enough for outdoor cats to become temporary indoor cats. It's even cold enough to affect the sharks!
