Ms. Mezzetti/APES Welcome to AP Environmental Science, AKA - APES! 'Unless someone like you cares a whole awful lot, nothing is going to get better. It's not.' The Lorax by Dr. Seuss The goal of this course is to provide students with the scientific principles, concepts, and methodologies to understand the interrelationships of the natural world, to identify and analyze environmental problems both natural and human-made, and to evaluate the risks associated with these problems and examine alternative solutions for resolving and/or preventing them. The AP Environmental Science course is designed to be the equivalent of a one-semester, introductory college course in environmental science. Unlike most other introductory-level college science courses, environmental science is offered from a wide variety of departments, including geology, biology, environmental studies, environmental science, chemistry, and geography. Depending on the department offering the course, different emphases are placed on various topics. Some courses are rigorous science courses that stress scientific principles and analysis and that often include a laboratory component; other courses emphasize the study of environmental issues from a sociological or political perspective rather than a scientific one. The AP Environmental Science course has been developed to be most like the former; as such, it is intended to enable students to undertake, as first-year college students, a more advanced study of topics in environmental science or, alternatively, to fulfill a basic requirement for a laboratory science and thus free time for taking other courses. The major topics of the class we will be covering this year are as follows: Science is a process. Science is a method of learning more about the world. Science constantly changes the way we understand the world. Energy conversions underlie all ecological processes. Energy cannot be created; it must come from somewhere. As energy flows through systems, at each step more of it becomes unusable. The Earth itself is one interconnected system. Natural systems change over time and space. Biogeochemical systems vary in ability to recover from disturbances. Humans alter natural systems. Humans have had an impact on the environment for millions of years. Technology and population growth have enabled humans to increase both the rate and scale of their impact on the environment. Environmental problems have a cultural and social context. Understanding the role of cultural, social and economic factors is vital to the development of solutions. Human survival depends on developing practices that will achieve sustainable systems. A suitable combination of conservation and development is required. Management of common resources is essential. Over the course of the year we will learn about the science and social issues associated with each of the above topics.

Cole takes a nap and gets a sticker when he gets up (yay stickers!) so the next day he takes a nap so that he will get another sticker c. Cole does not take a nap and has to go to bed 1 hour earlier meaning he misses out on taking a walk, so the next day he takes a nap so he can stay up for the walk – d. Cole throws a temper tantrum, which means that Mommy stops doing whatever she is doing and he gets to sit in Mommy’s lap and “talk” about what he did wrong and then Daddy “talks” to him about it later that night, so he keeps throwing temper tantrums so he can have Mommy and Daddy’s undivided attention e.
