CES 210 1st Edition Lecture 1Environmental Science Lecture OneWhat is Environmental Science?• Problems and Solutions• Complexity and Systems• Ways of “knowing” and Critical thinkingList of issues for President Obama• Economy, Healthcare, Energy, Education, Defense, Civil rights, Disabilities, Ethics, Family, Foreign policy, Homeland security, Immigration, Irag, Poverty, Rural, Service, Seniors and Social Security, Technology, Urban Veterans, and WomenUN Millennium Goals• Eradicate extreme poverty and hunger• Achieve universal primary education• Promote gender equality and empower women• Reduce child mortality• Improve maternal health• Combat HIV/AIDS and other disease• Ensure environmental sustainability• Develop a global partnership for developmentEnvironmental Science• It’s a systematic study of our environment• Includes all of the following: observation, identification, description, experimental investigation and theoretical explanation of phenomena (new advances in science and technology).• Whether or not you can prove anything in science• Its interdisciplinary• Broad field• Uses Ecology as a basic tool• Contains two goals…- Establish general principles about how the natural world functions- Identifying, understanding, and solving problemsWhat is Science?• Not just a body of knowledge• Dynamic process• Requires collection of data• An ongoing enterprise• Requires reevaluationTHE SCIENTIFIC METHOD (5 steps)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.1. Recognize problem or unanswered question2. Develop hypothesis to explain the problem• Make predictions based on hypothesis3. Design and perform experiment to test hypothesis4. Analyze and interpret data to reach conclusion• Does hypothesis predict reality?• If no, reject/revise hypothesis, start again• If yes, keep testing to verify hypothesis5. Share new knowledge with other scientists• New knowledge results in new questions• Other scientists will test hypothesisPerception VS Reality• What we “perceive as a problem doesn’t always match “objective: scientific reality• For example: odds of dying in a plane crash versus a car accident are 1/77The process of Science• A good hypothesis makes a prediction• Experiment contains two things- Variable: factor that influences a process- Control group: variable that isn’t altered• Theory - Integrated explanation of numerous hypothesis- Solid ground of science- Accepted as
