| Ecological Principles |
| 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" |
| 2. Energy primer |
a. Definition
b. Laws of energy
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. |

Carbon Adventures (game)
Source: Arizona State University GK-12 Down to Earth Science
web site and Margie
Winter, Fond du Lac School District
Web site with game:
http://gk12.asu.edu/node/45
Modified worksheet (MS Word)
Students learn what carbon is, the difference between
organic and inorganic carbon, the different carbon pools,
different forms carbon takes when it cycles, and how humans
influence the carbon cycle. The game is played in groups of four
using a game board, dice, and cards for various carbon pools.
Requires some prep time by the teacher the first use but can be
reused for several years. |
