HS-LS4-6 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 6 HS-LS4-6: Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.* [Clarification Statement: Emphasis is on designing solutions for a proposed problem related to threatened or endangered species, or to genetic variation of organisms for multiple species.]
HS-LS4-5 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 5 HS-LS4-5: Evaluate the evidence supporting claims that changes in environmental conditions may result in: (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. [Clarification Statement: Emphasis is on determining cause and effect relationships for how changes to the environment such as deforestation, fishing,…
HS-LS4-4 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 4 HS-LS4-4: Construct an explanation based on evidence for how natural selection leads to adaptation of populations. [Clarification Statement: Emphasis is on using data to provide evidence for how specific biotic and abiotic differences in ecosystems (such as ranges of seasonal temperature, long-term climate change, acidity, light, geographic barriers, or evolution of other organisms) contribute to a change in gene…
HS-LS4-3 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 3 HS-LS4-3: Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait. [Clarification Statement: Emphasis is on analyzing shifts in numerical distribution of traits and using these shifts as evidence to support explanations.] [Assessment Boundary: Assessment is limited to basic statistical and graphical analysis….
HS-LS4-2 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 2 HS-LS4-2: Construct an explanation based on evidence that the process of evolution 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…
HS-LS4-1 Evidence Statement
Life Science: Biological Evolution: Unity and Diversity – Evidence Statement 1 HS-LS4-1: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence. [Clarification Statement: Emphasis is on a conceptual understanding of the role each line of evidence has relating to common ancestry and biological evolution. Examples of evidence could include similarities in DNA sequences, anatomical structures, and order of appearance of structures in…
HS-LS3-3 Evidence Statement
Life Science: Heredity: Inheritance of Variation of Traits – Evidence Statement 3 HS-LS3-3: Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population. [Clarification Statement: Emphasis is on the use of mathematics to describe the probability of traits as it relates to genetic and environmental factors in the expression of traits.] [Assessment Boundary: Assessment does not include Hardy-Weinberg calculations.]
HS-LS3-2 Evidence Statement
Life Science: Heredity: Inheritance of Variation of Traits – Evidence Statement 2 HS-LS3-2: 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. [Clarification Statement: Emphasis is on using data to support arguments for the way variation occurs.] [Assessment Boundary: Assessment does not include the phases…
HS-LS3-1 Evidence Statement
Life Science: Heredity: Inheritance of Variation of Traits – Evidence Statement 1 HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. [Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.]
HS-LS2-8 Evidence Statement
Life Science: Ecosystems: Interactions, Energy, and Dynamics – Evidence Statement 8 HS-LS2-8: Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce. [Clarification Statement: Emphasis is on: (1) distinguishing between group and individual behavior, (2) identifying evidence supporting the outcomes of group behavior, and (3) developing logical and reasonable arguments based on evidence. Examples of group behaviors could include flocking, schooling, herding,…
