Biology/Life Sciences
Standard Set 6. Ecology
Stability in an ecosystem is a balance between
competing effects.
6.a. – Students know biodiversity is the sum total
of different kinds of organisms and is affected by
alterations of habitats.
6.b. – Students know how to analyze changes in an
ecosystem resulting from changes in climate, human
activity, introduction of nonnative species, or changes
in population size.
Standard Set 7. Evolution (Population Genetics)
The frequency of an allele in a gene pool of a
population depends on many factors and may be stable or
unstable over time.
7.d. – Student know variation within a species
increases the likelihood that at least some members of a
species will survive under changed environmental
conditions. (E.g. – Mediterranean Plant Adaptations)
Standard Set 8. Evolution (Speciation)
Evolution is the result of genetic changes that occur
in constantly changing environments.
8.a. – Students know how natural selection
determines the differential survival of groups of
organisms. (E.g. – Convergent evolution of Mediterranean
plant species.)
Earth Sciences
Standard Set 5. Energy in the Earth System (Ocean and
Atmospheric)
Heating of Earth’s surface and atmosphere by the
sun drives convection within the atmosphere and oceans,
producing winds and ocean currents.
5.a. – Student know how differential heating of
Earth results in circulation patterns in the atmosphere
and oceans that globally distribute the heat.
Standard Set 6. Energy in the Earth System (Climate
and Weather)
Climate is the long-term average of a region’s
weather and depends on many factors.
6.b. – Students know the effects on climate of
latitude, elevation, topography, and proximity to large
bodies of water and cold or warm ocean currents.
Standard Set 9. California Geology
The geology of California underlies the state’s
wealth of natural resources as well as its natural
hazards.
9.a. – Student know the resources of major economic
importance in California and their relation to
California’s geology.
