This lesson is part of the Athabasca University Astronomy 230: Northern Lights, Northern Skies course. In this lesson, you will learn how to identify the layers of the Earth’s atmosphere, how to describe the contents of each layer of the Earth’s atmosphere, and how to describe the importance of each of the layers of the Earth’s atmosphere.
This course has been designed to present astronomy and space science within a Canadian context. Unique phenomenon and astronomical events particular to Canada's northern latitude are highlighted and discussed. The course is divided into ten Unit modules. These are: The Night Sky; Planets and Orbits; Tools of the Astronomer; Earth, Moon, and Sun; Earth's Atmosphere; The Sun as a Star; Space Flight; Galaxies; Cosmology; Canadian Astronomy. Each Unit contains various self-directed Lessons designed to present the specific topics. Select multimedia elements and hands-on "try it" activities have been included to help augment the content.
The Earth is a dynamic system, constantly changing through a multitude of systems; the geologic, hydrologic, atmospheric and biologic systems are all integral to one another. Despite the fact that we inhabit this blue planet many of us are unaware of how even the simplest of systems work between one another and how even a small perturbation in one system can ripple through them all. The curriculum that follows will outline the systems of the earth and draw upon their interconnectedness to bring about a new found understanding of our environment and the critical modern day issues we are facing now and in the future. Through a multitude of hands-on and investigative lessons and activities this series will help students take their prior knowledge and combine it with new understandings and conflicts to ultimately apply the information gained in the local communities for a culminating environmental action project.
This curriculum is meant for students who have already progressed through some earth science classes. There are many lessons within the collection that can be pulled out and used separately from the curriculum as a whole.
The 5th Unit covers many topics addressed in a book called The Revenge of Gaia: Earth's Climate Crisis & The Fate of Humanity, by James Lovelock, 160 pages with glossary. I recommend this as a reading for the semester, especially during Unit 5 though it is not a requirement to follow the science or the lessons.
