Why Stability and Change The Concept of Change Benchmarks, NSES, 1996 NAEP Is change certain? Relationship to time The Concept of Stability Benchmarks, NSES, 1996 NAEP Stability (e.g., equilibrium, homeostasis)
25
Stability and Change Constancy and Change In the AAAS Benchmarks for Science Literacy (1995) – Constancy and change is included as one of the four common themes. In the National Science Education Standards (1996) – Unifying themes and principles include constancy and change as well as evolution and equilibrium.
26
Stability and Change Change as the natural result of time Rate of change Stability Stability at one scale of time, size, or distance is change at another scale
27
Provide an example of a science phenomenon in which the concept of stability is useful for students to construct an explanation. Please share your example in the chat window. Also type in your questions. Reflection and Questions

“Change” in the NGSS Performance Expectations 4-PS3-3. Ask questions and predict outcomes about the changes in energy that occur when objects collide. MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. HS-ESS2-2. Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth’s systems.

32
The Framework is Designed to Help Realize a Vision of Science Education Science education in which all students’ experiences over multiple years foster progressively deeper understanding of science. Students actively engage in scientific and engineering practices in order to deepen their understanding of crosscutting concepts and disciplinary core ideas. In order to achieve the vision embodied in the Framework and to best support students’ learning, all three dimensions should to be integrated into the system of standards, curriculum, instruction, and assessment. NRC Framework Page 217
33
Structure/Dimensions of the Framework Science and Engineering Practices Crosscutting Concepts Disciplinary Core Ideas “ The three dimensions of the Framework, which constitute the major conclusions of this report, are presented in separate chapters. However, in order to facilitate students’ learning, the dimensions must be woven together in standards, curricula, instruction, and assessments. When they explore particular disciplinary ideas from Dimension 3, students will do so by engaging in practices articulated in Dimension 1 and should be helped to make connections to the crosscutting concepts in Dimension 2.” NRC Framework Pages 29 - 30

35
What are Crosscutting Concepts? Crosscutting Concepts scaffold across disciplinary boundaries and contribute to sense making and support students in valuing and using science and engineering practices. The Framework describes seven crosscutting concepts that support understanding of the natural sciences and engineering. The crosscutting concepts, when made explicit for students, contribute to their understanding of a coherent and scientifically-based view of the world. Crosscutting concepts have utility for instruction. Framework Page 83
36
Crosscutting Concepts and Instruction Although crosscutting concepts are fundamental to an understanding of science and engineering, students have often been expected to build such knowledge without any explicit instructional support. Hence the purpose of highlighting them as Dimension 2 of the Framework is to elevate their role in the development of standards, curricula, instruction, and assessments. Crosscutting concepts should become common and familiar touchstones across the disciplines and grade levels. Explicit reference to the concepts, as well as their emergence in multiple disciplinary contexts, can help students develop a cumulative, coherent, and usable understanding of science and engineering.

Crosscutting Concepts The Framework has identified seven key Crosscutting Concepts that serve a variety of purposes in science. This is one way to organize them for instruction.
42
Using Crosscutting Concepts to Make Sense of Phenomena Geologists have found patterns in the rock layers Sedimentary rock provides evidence of changes over time in what appears to be a static condition
43
Stability Stability denotes a condition in which some aspects of a system are unchanging, at least at the scale of observation. Stability means that a small disturbance will fade away— that is, the system will stay in, or return to, the stable condition. Such stability can take different forms, with the simplest being a static equilibrium, such as a ladder leaning on a wall. By contrast, a system with steady inflows and outflows (i.e., constant conditions) is said to be in dynamic equilibrium. Framework 98-99
44
Stability in Cycles A repeating pattern of cyclic change—such as the moon orbiting Earth—can also be seen as a stable situation, even though it is clearly not static. Such a system has constant aspects, however, such as the distance from Earth to the moon, the period of its orbit, and the pattern of phases seen over time. Framework 98-99
45
Designed Stability Systems are often designed for stable operation Feedback loops are used to trigger an action that causes a change back to a desired stable condition: – Thermostat control feedback to furnace or AC to control temperature – Float on tank control feedback to valve to control water level in tank Feedback
46
Stability, Change and Time A system may be described as stable at one time scale but changing at another scale (e.g., geologic formations, climate, ecosystems, populations) Understanding “Change” as a concept may require understanding deep time. “An understanding of geologic history and the history of life requires a comprehension of time that initially may for some be disconcerting.” James Hutton proposed the ideas of deep time in the 18 th century. One of his Hutton’s contemporaries, John Playfair, while on a field trip with Hutton to study the unconformity in the rock formations at Siccar Point Scotland stated: “the mind seemed to grow giddy by looking so far into the abyss of time.”
47
Causality and Change Changes have causes that can be described. Determining the “cause and effect” relationships in systems often requires students to seek the causes of changes. The practice of “constructing explanations” for phenomena often focuses on describing the mechanisms of observed changes in a system.
48
Systems and Change Stability and changes are often used in describing or defining a system. Stability and change are useful for developing understanding of the scale of systems. Useful questions about systems provide insights into the nature of the system: – “How is the system changing?” – “What is the rate of change of the system?” – “What is causing the change in the system?” “
49
Patterns and Change Observing changes in systems is an important way students are able to determine patterns
