Next Generation Science Standards Addressed:

  • Disciplinary Core Ideas:
    1. LS3.A Inheritance of Traits
    2. LS3.B Variation of Traits

  • Practices:
    Developing and Using Models

  • Cross-Cutting Concepts:
    Patterns: Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.
