I wrote this unit over the past five years that I have taught Earth Environmental Science for Freshmen and Sophomores (it can also be used for other levels). The bundle includes notes, lectures, tests, quizzes, review, labs - everything you need! Every file is completely editable. Study guides can be customized to your specific reading assignments to your students. NGSS standards available upon request. Challenge your students with rigor and stimulating lessons! Topics include: composition of atmosphere, layers, energy transfer, properties, clouds, etc. Duration of unit varies depending on depth and number of labs/activities you use. Files are neatly organized into folders by lesson/resource type.
