SCI.LS1 Students use science and engineering practices, crosscutting concepts, and an understanding of structures and processes (on a scale from molecules to organisms) to make sense of phenomena and solve problems.
SCI.LS1.B Growth and Development of Organisms
SCI.LS1.B.3 Reproduction is essential to every kind of organism. Organisms have unique and diverse life cycles.
SCI.LS2 Students use science and engineering practices, crosscutting concepts, and an understanding of the interactions, energy, and dynamics within ecosystems to make sense of phenomena and solve problems.
SCI.LS2.C Ecosystem Dynamics, Functioning, and Resilience
SCI.LS2.C.3 When the environment changes, some organisms survive and reproduce, some move to new locations, some move into transformed environments, and some die.
SCI.LS2.D Social Interactions and Group Behavior
SCI.LS2.D.3 Being part of a group helps animals obtain food, defend themselves, and cope with changes.
SCI.LS3 Students use science and engineering practices, crosscutting concepts, and an understanding of heredity to make sense of phenomena and solve problems.
SCI.LS3.A Inheritance of Traits
SCI.LS3.A.3 Many characteristics of organisms are inherited from their parents. Other characteristics result from individuals' interactions with the environment. Many characteristics involve both inheritance and environment.
SCI.ETS Engineering, Technology, and the Application of Science
SCI.ETS1 Students use science and engineering practices, crosscutting concepts, and an understanding of engineering design to make sense of phenomena and solve problems.
SCI.ETS1.A Defining and Delimiting Engineering Problems
SCI.ETS1.A.3-5 Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account.
SCI.ETS2 Students use science and engineering practices, crosscutting concepts, and an understanding of the links among Engineering, Technology, Science, and Society to make sense of phenomena and solve problems.
SCI.ETS2.A Interdependence of Science, Engineering, and Technology
SCI.ETS2.A.3-5.i Science and technology support each other.
SCI.ETS2.A.3-5.ii Tools and instruments are used to answer scientific questions, while scientific discoveries lead to the development of new technologies.
SCI.ETS2.B Influence of Engineering, Technology, and Science on Society and the Natural World
SCI.ETS2.B.3-5.i People's needs and wants change over time, as do their demands for new and improved technologies.
SCI.ETS2.B.3-5.ii Engineers improve existing technologies or develop new ones to increase their benefits, decrease known risks, and meet societal demands.
SCI.ETS2.B.3-5.iii When new technologies become available, they can bring about changes in the way people live and interact with one another.
SCI.ETS3 Students use science and engineering practices, crosscutting concepts, and an understanding of the nature of science and engineering to make sense of phenomena and solve problems.
SCI.ETS3.A Science and Engineering Are Human Endeavors
SCI.ETS3.A.3-5.i Science and engineering knowledge have been created by many cultures.
SCI.ETS3.A.3-5.ii People use the tools and practices of science and engineering in many different situations (e.g., land managers, technicians, nurses and welders).
SCI.ETS3.A.3-5.iii Science and engineering affect everyday life.
SCI.ETS3.B Science and Engineering Are Unique Ways of Thinking with Different Purposes
SCI.ETS3.B.3-5.i Science and engineering are both bodies of knowledge and processes that add new knowledge to our understanding.
SCI.ETS3.B.3-5.ii Scientific findings are limited to what can be supported with evidence from the natural world.
SCI.ETS3.B.3-5.iii Basic laws of nature are the same everywhere in the universe (e.g., gravity, conservation of matter, energy transfer, etc.).
SCI.ETS3.B.3-5.iv Engineering solutions often have drawbacks as well as benefits.
SCI.ETS3.C Science and Engineering Use Multiple Approaches to Create New Knowledge and Solve Problems
SCI.ETS3.C.3-5.i The products of science and engineering are not developed through one set "scientific method" or "engineering design process." Instead, they use a variety of approaches described in the Science and Engineering Practices.
SCI.ETS3.C.3-5.ii Science explanations are based on a body of evidence and multiple tests, and describe the mechanisms for natural events. Science explanations can change based on new evidence.
SCI.ETS3.C.3-5.iii There is no perfect design in engineering. Designs that are best in some ways (e.g., safety or ease of use) may be inferior in other ways (e.g., cost or aesthetics).
