Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What is the independent variable?
pH of soil
Appreciating a river for its rugged beauty is an _______________ value
intrinsic
Joe counted the snails in 4 of 20 blocks of his field. The total counted was 60 worms. What would he predict to be the total number of worms in the entire field?
300 worms
The difference between non-renewable and renewable resources

Non-renewable: Finite resource
Which period of human history has created the most water pollution?

Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
The number of strawberries produced is known as
the dependent variable
The cost of environmental solutions can be high. To determine how much to spend on air pollution, a community may perform a ______ -______ ___________.
Cost - benefit analysis
What sampling method(s) are useful for mobile animals?
Mark and recapture
An environmental ethic that places an emphasis on short term human interest
Anthropocentric
Most of today's environmental problems began during which period(s) in human history?
Industrial Revolution
Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What are 3 constants in this experiment?
Answers will vary. EX: size of pot; amount of water, type (species) of strawberry, source of soil, where grown (light, temperature, etc.)
Two extrinsic values of the James River
Answers will vary. EX: Fish; barge transportation; fresh water; river rafting excursions (businesses)
What sampling method(s) are used for stationary species
Quadrats and Transects
Conflict due to overuse of SHARED resources
Tragedy of the commons
What was the environmental impact of the Agricultural Revolution?
Decreased biodiversity (due to focus on a few crops) and increased habitat destruction (due to increased population).
Jane wants to study the effect of pH on strawberry production. She grows the same type of strawberry plants in soils of different pH, and counts the number of strawberries produced over one growing season.
What might Jane's hypothesis be?
ANSWERS will vary, but must be quantitative and include a trend. EXAMPLE: As the pH decreases, the number of strawberries produces will decrease.
According to the law of supply and demand, if the amount of oil extracted worldwide were to increase and demand stayed the same, the price of oil should _____.
Decrease
A non-random sampling method
transects
