Earth Science Documents
The powerpoints, notes, and some worksheets are from Glencoe. I have modified some of them, but they are still the work of Glencoe, unless otherwise noted.
Remember to select handouts or notes pages, when you print powerpoint presentations, to save paper. The options are on the print options screen. The notes are the same ones I use in class.
