[1] Please start each night’s homework at the top of a new page, and number each day 1, 2, 3…etc. Put the solutions to the energy sheet with that day’s homework. This will make it easier to grade. If you are lost – look at it as a creative writing assignment – write about specifically what you don’t understand…
