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 […]

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 […]

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, […]

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 […]

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) […]

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 […]

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 […]

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 […]

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 […]

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 […]
