COMPOSED OF CELLS
EVOLUTION THROUGH NATURAL SELECTION
USE ENERGY

REPRODUCE
DNA
RESPOND TO ENVIRONMENT
o Apply the eight characteristics of life to explain why an
organism is alive and how it utilizes those characteristics.
o Define cell “differentiation.” SEE ABOVE DEFINITION
o Define “homeostasis.”
o Define “biodiversity.”
o List the four levels of biodiversity
GENETIC: EYE COLOR OF HUMANS
POPULATION: HUMANS IN WEST MILTON
SPECIES:HUMANS
ECOSYSTEM: DECIDUOUS FOREST, TUNDRA, DESERT, RAIN
FOREST
o Provide an example of each of the four levels of
biodiversity.
o State the five biggest threats to biodiversity in our world.
H= Habitat Loss
I= Invasive Species
2
P=Pollution
P= Population Growth
O= Overuse of Resources
o Explain how species diversity is decreased by human
disturbance under most circumstances.
o Create and interpret a species accumulation graph to
illustrate the species richness of a habitat.
o Correlate the relationship between species diversity,
habitat diversity and ecosystem size.
THE BIGGER THE ECOSYSTEM, THE MORE THE SPECIES
DIVERSITY, AND THE MORE VARIETY OF HABITATS, THE
MORE SPECIES DIVERSITY.
o Identify habitat fragmentation as having the most negative
impact on biodiversity.
o Define “deforestation” and its impact on biodiversity.
o Give examples of events that destroy habitats and offer
alternative solutions to those events.
o Simulate how the number of species on habitat islands is
affected by the area effect and the distance effect; closer
and larger islands to the source population have more
species.
o Describe edge effects as the physical and biological
conditions that change the habitat such that the area on
3
the border cannot support the same species as the interior
of the habitat.
o Analyze the effectiveness of a nature reserve by taking
into account edge effects.
o Give a brief history of our local woods and describe the
characteristics of some of the dominant plant forms in our
local woods.
DECIDUOUS FOREST SO IT IS COMPOSED OF TREES THAT
LOSE THEIR LEAVES IN THE WINTER.
NONNATIVES INCLUDE HONEYSUCKLE, GARLIC MUSTARD,
NORWAY MAPLES.
NATIVES INCLUDE POKEWEED, SUGAR MAPLE, AMERICAN
BEECH, POISON IVY, BLOODROOT, WATERLEAF. LOWRY
CONSISTS OF TWO PARTS: CLIMAX AND SUCCESSION
FOREST.
o Give examples of how non-native, or exotic, species get
introduced by humans, whether purposefully or
accidentally.
o Define an “ invasive species.”
o Explain how invasive species can be detrimental to
biodiversity.
o Design an experiment to test whether or not honeysuckle,
an exotic species, is also an invasive species.
4
o Create a food web to show energy transfer in a given set
of organisms in an ecosystem
o Place a given set of organisms on a trophic pyramid
o Identify each level of a trophic pyramid
o Define “biological magnification.”
o Simulate biological magnification to show how organisms
at the top of the trophic pyramid are most negatively
affected by toxins (Use DDT as your example).
o Use a Dissolved Oxygen Probe to measure the
concentration of dissolved oxygen in water
o Study the effect of temperature on the amount of
dissolved oxygen in water.
o Predict the effect of water temperature on aquatic life
o Locate a possible source of pollutants along a river or
stream and also track the water quality of the source of
drinking water by making measurements periodically at
the same location at different times of the day
o Perform four of the nine WQI tests: (Water temperature,
Dissolved Oxygen, pH, and Total Dissolved Solids)
o Calculate the water quality of a local body of water
o Give examples of the causes of atmospheric pollution and
freshwater pollution
5
o Explain how the Industrial Revolution impacted the
pollution levels of the atmosphere
o Define “greenhouse gases.”
o Explain how greenhouse gases contribute to global
warming.
o Distinguish between point source pollution and nonpoint
source pollution.
o Describe the contents of smog and how smog contributes
to the formation of acid rain.
o Simulate different solutions to observe how hydrogen ion
concentration affects pH.
o Interpret whether is a material is acidic, neutral, or basic
using a pH sensor.
