    Heredity: Inheritance and Variation of Traits

Students who demonstrate understanding can:

Performance Expectations

  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. HS-LS3-1

    Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

Common Core State Standards Connections

ELA/Literacy

  • RST.11-12.1 - Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account. (HS-LS3-1)
  • RST.11-12.9 - Synthesize information from a range of sources (e.g., texts, experiments, simulations) into a coherent understanding of a process, phenomenon, or concept, resolving conflicting information when possible. (HS-LS3-1)

  • More resources added each week!
    A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
  • This computer simulation allows students to investigate the relationship between DNA sequences and protein structures.  Additionally, this interactive activity allows students to make sense of the relationship between DNA structure and types of ...

  • This two-minute video provides brief background on the use of zebrafish as a model in studying animal development, before showing a time-lapse sequence of a fertilized zebrafish egg developing into a larva.  The video includes some annotations t ...

  • This resource is an article from the January 2016 issue of The Science Teacher.  The unit focuses on an essential question:  How do Siamese cats develop their coloration?  Students develop explanations by making connections among ...

  • In this activity students analyze a family’s pedigrees to make a claim based on evidence about mode of inheritance of a lactose intolerance trait, determine the most likely inheritance pattern of a trait, and analyze variations in DNA to make a claim ...

  • This lab activity introduces students to the process of meiosis at the chromosomal level. The guiding question for the investigation is: How does the process of meiosis reduce the number of chromosomes in reproductive cells? Students develop an exp ...

  • Extra! Extra! Hot off the presses! Presenting newly released and FREE classroom-ready resources and strategies for incorporating infectious diseases and viruses in your classroom. All of these HHMI BioInteractive resources are aligned with the NGSS, ...

  • Students will compare and contrast methods of selective plant breeding, describe the scientific process of creating a genetically modified plant, compare genetically modified soybean seeds to conventional soybean seeds, describe the impact weeds have...

  • These are the Slide for "Beyond Earlobes and Tongue Rolling"

  • In this lab activity, students use a chemical indicator (bromothymol blue) to detect the presence of carbon dioxide in animal and plant respiration and in the burning of fossil fuels and its absence in the products of plant photosynthesis. After com...

  • This overview provides a sequence of learning activities to help students understand that proteins and DNA are not just abstract concepts in biology textbooks, but rather crucial components of our bodies that affect functions and characteristics that...

  • In this hands-on, minds-on activity, students use model chromosomes and answer analysis and discussion questions to learn about the processes of meiosis and fertilization. As they model meiosis and fertilization, students follow the alleles of a huma...

  • In this hands-on, minds-on activity students learn (1) how genes provide the instructions for making a protein via transcription and translation and (2) how genes influence characteristics such as albinism and sickle cell anemia. Students use simple ...
