,Environmental science explores.... - ANS interactions between humans and the physical and
biological world
What is science and how does it work? - ANS A systematic process for learning about the
world and testing our understanding of it. The accumulated body of knowledge that arises from
this dynamic process.
The scientific method - ANS Testing ideas through observation,
questioning, and experimentation
Assumptions used in science? - ANS The universe works according to natural laws. Events
arise from causes, and cause other events. We use logic, systematic testing, and our senses to
understand natural laws.
Steps of the scientific method - ANS 1. observations
2. questions
3. hypothesis
4. predictions
5. test
6. Results
Interpret test results means... - ANS to support or reject the hypothesis
Millennium Ecosystem
Assessment - ANS comprehensive scientific assessment of the state of the world's
ecosystems and their ability to support life and civilization

,Millennium Ecosystem
Assessment: Major Findings - ANS Rapid, extensive changes in the past 50 years; likely to
worsen, Substantial and irreversible loss in biodiversity, Net gains in human
development/economies, but at a cost, Reversing the degradation of ecosystems will require
significant changes
What are root problems of the environment? - ANS Population, poverty,
and over-consumption
Sustainable development - ANS use of resources to satisfy current needs without
compromising future availability of resources
Sustainability - ANS conserves Earth's natural resources & maintains fully functioning
ecological systems. The center of economic, environmental, and social
what is a hypothesis? - ANS A provisional statement that proposes a possible explanation for
a particular observed phenomenon
what is a null hypothesis? - ANS A statement of "no effect"
Predictions - ANS what you expect to happen if your hypothesis is true (in terms of
measurable results)
good study designs... - ANS have adequate samples sizes, are unbiased, are achievable, have
some kind of comparison (to a relevant control group, to previous conditions, etc.), and are
ethical

, SMART - ANS Specific, measurable, achievable, realistic, and time-bound
example of unfalsifiable hypothesis - ANS "Belugas in the St Laurence River are
dying because it is part of God's plan."
example of untestable hypothesis - ANS "The belugas are dying because they are susceptible
to an undetectable radio frequency that is being picked up in their fat cells which disrupts their
endocrine system."
The Nebular Hypothesis - ANS explains the origin of the solar
system
Nebular hypothesis: Summary of steps - ANS 1. Interstellar cloud of gas and dust
2. Rotation, flattened disc
3. Pressure, temperature gradient
4. Nuclear fusion in the Sun: Solar nebula
5. Condensation of materials
6. Accretion of objects
7. Differentiation
Jovain Planets - ANS Outer planets, including Neptune, Uranus, Saturn, Jupiter. Huge,
gaseous, and icy.
Terrestrial planets - ANS inner planets, including mars, earth, Venus, and mercury. Small,
rocky, and metallic
