Unit Overview/Summary:  Summary  The unit organizes performance expectations with a focus on helping students build understanding of traits of organisms. Instruction developed from this unit should always maintain the three-dimensional nature of the standards and recognize that instruction is not limited to the practices and concepts directly linked with any of the unit performance expectations. Connections between unit Disciplinary Core Ideas (DCIs)  NGSS Disciplinary Core Ideas (DCIs ) are fundamental scientific ideas that form the content of an NGSS curriculum.  They cover four domains: physical science, life science, earth, and space science, as well as engineering, technology, and applications of science. NGSS core ideas represent the main domains of factual understanding that students should develop within each discipline.The idea that being part of a group helps animals obtain food, defend themselves, and cope with changes (LS2.D as in 3-LS2-1) connects to the idea that reproduction is essential to the continued existence of every kind of organism (LS1.B as in 3-LS1-1) through the concept of survival of organisms. Reproduction also connects to the concept of inheritance and that many characteristics of organisms are inherited from their parents (LS3.A as in 3-LS3-1). Other characteristics result from individuals’ interactions with the environment, which can range from diet to learning. Many characteristics involve both inheritance and environment (LS3.A as in 3-LS3-2).  All the previous concepts also connect to each other through the concept of patterns: patterns of reproduction and life cycles across organisms, and patterns of characteristics of organisms, both inherited and from interactions with the environment. The concept of patterns also allows students to begin studying the idea that scientists record patterns of the weather across different times and areas so that they can make predictions about what kind of weather might happen next (ESS2.D as in 3-ESS2-1). This idea will be further developed in subsequent unit. Unit Science and Engineering Practices (SEPs)The practices describe behaviors that scientists engage in as they investigate and build models and theories about the natural world and the key set of engineering practices that engineers use as they design and build models and systems.Instruction leading to this unit of performance expecations (PEs) will help students build toward proficiency in elements of the practices of developing and using models (3-LS1-1), analyzing and interpreting data (3-LS3-1 and 3-ESS2-1), constructing explanations and designing solutions (3-LS3-2), and engaging in argument from evidence (3-LS2-1). Many other practice elements can be used in instruction. Unit Crosscutting Concepts (CCCs)Crosscutting concepts have value because they provide students with connections and intellectual tools that are related across the differing areas of disciplinary content and can enrich their application of practices and their understanding of core ideas. As such, they are a way of linking the different domains of science.Instruction leading to this unit of performance expecations (PEs) will help students build toward proficiency in elements of the crosscutting concepts of Patterns (3-LS1-1, 3-LS3-1, and 3- ESS2-1) and Cause and Effect (3-LS2-1 and 3-LS3-2). Many other crosscutting concepts elements can be used in instruction. All instruction should be three-dimensional.
