Main Objectives:

Students will analyze the relationships in an

ecosystem. Population size, biotic factors,

disease, and resource depletion will be

investigated.

Learning Outcomes: Students should observe mathematical representations of population components, including numbers and types of organisms, boundaries, resources, climate, or population changes, in forms such as graphs, histograms, averages, or even spreadsheet-based data. From such mathematical representations, students should make and support claims regarding the influences of factors (boundaries, resources, climate, and competition) on the ecosystem.

Main Objective: Biogeochemical cycles include the movement of matter through both living and non-living systems and the transformation of elements between usable and unusable forms. Living organisms must incorporate matter from their surroundings in order to grow. Some organisms are able to fix elements directly from the atmosphere such as plants through photosynthesis, or bacteria through nitrogen fixation. Learning outcomes: Students focus should be on understanding that fixation or abiotic processes permit the production of usable forms of the elements needed to support life. Understanding of these processes is vital to successful agricultural processes that can overuse some resources, creating imbalances in ecosystem dynamics and highly developed interspecific dependencies.

Main objective: Matter is not created nor destroyed, but transferred throughout our ecosystem. In addition, it should be recognized that energy transfer is inefficient with loss of approximately 90% at each trophic level transfer. Students will track energy through trophic levels, and determine if organisms are produces or consumers. Students will create a model that illustrates the “10% rule.”

Learning Outcomes: Students should use mathematical models (graphs, data tables, histograms) should incorporate ecosystem information including the organisms, energy, matter, and food web, including how both energy and matter cycle in the ecosystem. The models should account for the way that both matter and energy transfer between different organisms in the ecosystem as well as between organisms and the physical environment. Energy and matter transferred to the physical environment should include both energy used by organisms as part of actively sustaining life, and energy that is not recaptured when an organism dies and decays. Students should consider the laws of conservation of energy and matter, an explanation should strive to explain how and where energy and matter transfer from the organic pools in each trophic level.

variation. Asexual reproduction results in

offspring with traits identical to the parent, with

Learning outcomes:

Student emphasis should be placed on events that lead to genetic differences (mutations, crossing over, random segregation of alleles, independent assortment, and random fertilization) and explanations for how the mechanisms of DNA replication and transmission lead to organisms that resemble their parents.

Student models of meiosis should be useful in demonstrating how chromosome-based diseases such as Trisomy 21 occur or how sterile hybrids (e.g., mules or seedless watermelons) cannot complete meiosis due to non-homologous DNA from different parent species

Main Objective: This standard is designed to

complete the connection between genotypes,

protein synthesis, and resulting phenotypes by

examining concrete examples. It should become

clear that recessive traits occur when neither

diploid copy of a gene produces a functional

protein.

Examples: PTC taster, ABO blood types

Learning outcomes:

Students could research the cause of specific and relatively simple examples of monogenic traits Students should recognize that phenotypic variation arises not only from genotypic variation, but also from gene expression variation, the latter of which can often be the result of environmental influences.

Main Objective: Students will expand upon

knowledge of Punnett squares. Students will

become fluent in pedigree creation and

analysis. Modes of inheritance should include

autosomal and sex-linked genes that are

dominant/recessive, codominant, or

incompletely dominant.

Learning Outcomes: Students can practice deductive reasoning using a basic set of criteria (including successive generation transmission and male/female ratio) in order to predict a mode of inheritance for a trait, define alleles for the trait, and assign genotypes to the family members of a given pedigree. Students can also practice using probability-based mathematics to predict offspring genotypes and phenotypes based on a given parental set.

Main Objective: Students will discover the

importance of biodiversity, and determine how

humans are negatively impacting biodiversity.

Discussing human activities draws this

conversation to a larger scale. The loss of

biodiversity or species has the same impact

globally as it would at ecosystem levels.

Natural selection is expedited by significant

changes to ecosystems. Without deliberate

efforts, human development causing habitat

loss can be the significant change wiping out

ecosystems.

Learning Outcomes: Students should appreciate that biodiversity increases with preservation of evolutionary lineages (decreased extinction rates) and in a feed-forward mechanism, biodiversity promotes ecosystem stability, which decreases extinction rates. Students can investigate the various levels of biodiversity (genetic, species, ecosystem) required to provide services such as food, medicine, water purification, pollination, etc. and maintain ecosystem stability through climate stabilization, waste decomposition, maintenance of interdependent relationships, etc.

different scales.

SCIENCE AND ENGINEERING PRINCIPLE:

Asking questions (for science) and defining problems (for engineering)

Questions about arguments and interpretations should elicit further elaboration or investigation.
