| 1. Commoner's laws of ecology |
a.
"Everything is connected to
everything else"
b. "Everything must go somewhere"
c. "Nature knows best"
d. "There is no such thing as a free lunch" |

c. Types of energy |
| 3. Evolution |
a.
Natural selection
b. Environmental adaptations and ecological
niche
c. Speciation, biodiversity, co-evolution,
extinction
d. Rates of evolution - gradualism vs.
punctuated equilibrium |
| 4. Organismal ecology |
a.
Unit of natural selection –
survival and
reproduction
b. Kingdoms of life and requirements for life
c. Habitat, environmental adaptations, and
ecological niche
d. Homeostasis and feedback regulation –
thermoregulation, osmoregulation, gas
exchange, energetics
e. Cellular metabolism – photosynthesis,
cellular respiration,
chemosynthesis
|
| 5.
Population ecology |
a. Population dynamics – exponential vs.
logistic growth
b. Carrying capacity and limiting factors
c. Population structure –
age, gender,
survivorship
d. Population genetics and genetic diversity |
| 6. Community ecology |
a.
Species interactions – resource
competition, predation,
symbiosis
b. Competitive exclusion principle
c. Niche partitioning and keystone species
d. Species biodiversity
e. Ecological succession – primary vs.
secondary
f. Disturbance |
| 7. Ecosystem ecology |
a.
Matter/Biogeochemical cycles
(biotic/abiotic) – water,
carbon, nitrogen,
phosphorous, sulfur
b. Energy flow – trophic levels, food
pyramids, food webs
c. Thermodynamics – 1st law (conservation
of energy) and 2nd law
(entropy)
d. Biomes – environmental factors influencing
distribution
e. Value of ecosystem services |
| 8.
Biosphere ecology |
a. Global energy flow – solar input,
ocean
currents, air mass circulation
b. Global matter cycling – global
biogeochemical cycles
c. Global biodiversity – species distribution
and abundance
d. Plate tectonics – theory of continental drift
e. Global environmental issues – extinction
crisis, climate
change, etc. |

Plate Tectonics Story (activity)

Verona Area High School and US Geological Survey
Activity (MS Word)
Web site
In this activity, students use the Dynamic Earth
web site to research plate tectonics and write a story
describing the theory. The web site is divided into 8 chapters
containing sub topics and diagrams relevant to the main topic. |

This Dynamic Earth: The Story of Plate Techtonics
(web site)

PDF
Online version of a 1996 book by J. Kious and R. Tilling. Gives
a brief introduction to the concept of plate tectonics and
highlights some of the people and discoveries that advanced the
development of the theory and traces its progress since its
proposal. Although the general idea of plate tectonics is now
widely accepted, many aspects still continue to confound and
challenge scientists. |
