13 HS-LS3-2: Students will make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. Prior Background Knowledge predict traits of offspring using Punnett Square. Students will know: chromosome number (e.g. diploid, haploid) DNA replication mutations (inherited, random and environmental) lead to variations (i.e. beneficial, harmful and neutral mutations) genetic variation through sexual reproduction (e.g. crossing over, independent assortment, random fusion of gametes) changes in DNA can lead to genetic diversity. describe how meiosis results in genetic variation of offspring. argue how changes in DNA lead to different traits. defend the claim that crossing over, independent assortment, and random fusion of gametes results in the diversity of organisms. relate mutation to genetic variation.

Board Adopted March 27,

16 HS-LS4-2: Students will construct an explanation based on evidence that the process of evolution by natural selection primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment. Prior Background Knowledge analyze data from multiple sources to explain relationships between variables affecting natural selection.

18 *HS-LS4-5: Students will evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) changes in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species, including American Indian perspectives.(iefa) Prior Background Knowledge N/A Students will know: environmental change causes population change Vocabulary speciation extinction environmental change is both good and bad for species. compare and contrast environmental factors that lead to (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. evaluate the impact of species extinction.
