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.B Developing Possible Solutions

      • SCI.ETS1.B.3-5.i Research on a problem should be carried out before beginning to design a solution. Testing a solution involves investigating how well it performs under a range of likely conditions.

      • SCI.ETS1.B.3-5.ii At whatever stage, communicating with peers about proposed solutions is an important part of the design process, and shared ideas can lead to improved designs.

      • SCI.ETS1.B.3-5.iii Tests are often designed to identify failure points or difficulties, which suggest the elements of the design that need to be improved.

    • SCI.ETS1.C Optimizing the Design Solution

  • 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).
