Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved. Students in high school continue to develop their understanding of the four core ideas in the physical sciences. These ideas include the most fundamental concepts from chemistry and physics but are intended to leave room for expanded study in upper-level high school courses. The high school performance expectations in the physical sciences build on middle school ideas and skills and allow high school students to explain more in-depth phenomena central not only to the physical sciences but to the life and earth and space sciences as well.
In the physical sciences performance expectations at the high school level, there is a focus on several scientific practices. Students are expected to develop understanding of the substructure of atoms and to provide more mechanistic explanations of the properties of substances. Chemical reactions, including rates of reactions and energy changes, can be understood by students at this level in terms of the collisions of molecules and the rearrangements of atoms.
Students are able to use the periodic table as a tool to explain and predict the properties of elements. Using this expanded knowledge of chemical reactions, students are able to explain important biological and geophysical phenomena. Phenomena involving nuclei are also important to understand, as they explain the formation and abundance of the elements, radioactivity, the release of energy from the sun and other stars, and the generation of nuclear power.
Students are also able to apply an understanding of the process of optimization in engineering design to chemical reaction systems. The crosscutting concepts of patterns, energy and matter, and stability and change are called out as organizing concepts for these disciplinary core ideas. In the PS1 performance expectations, students are expected to demonstrate proficiency in developing and using models, planning and conducting investigations, using mathematical thinking, and constructing explanations and designing solutions and to use these practices to demonstrate understanding of the core ideas.
The performance expectations. Students also develop understanding that the total momentum of a system of objects is conserved when there is no net force on the system. Students are able to apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision. The crosscutting concepts of patterns, cause and effect, systems and system models, and structure and function are called out as organizing concepts for these disciplinary core ideas.
In the PS2 performance expectations, students are expected to demonstrate proficiency in planning and conducting investigations, analyzing data and using math to support claims, applying scientific ideas to solve design problems, and communicating scientific and technical information and to use these practices to demonstrate understanding of the core ideas.
Energy is understood as a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system, and the total change of energy in any system is always equal to the total energy transferred into or out of the system. Students develop an understanding that energy at both the macroscopic and the atomic scales can be accounted for as either motions of particles or energy associated with the configuration relative positions of particles. In some cases, the energy associated with the configuration of particles can be thought of as stored in fields.
Students also demonstrate their understanding of engineering principles when they design, build, and refine devices associated with the conversion of energy. The crosscutting concepts of cause and effect; systems and system models; energy and matter; and the influence of science, engineering, and technology on society and the natural world are further developed in the performance expectations associated with PS3.
In these performance expectations, students are expected to demonstrate proficiency in developing and using models, planning and carry out investigations, using computational thinking, and designing solutions and to use these practices to demonstrate understanding of the core ideas. The performance expectations associated with PS4: Waves and Their Applications in Technologies for Information Transfer are critical to understand how many new technologies work.
Students are able to apply understanding of how wave properties and the interactions of electromagnetic radiation with matter can transfer information across long distances, store information, and investigate nature on many scales. Models of electromagnetic radiation as either a wave of changing electrical and magnetic fields or as particles are developed and used.
Students understand that combining waves of different frequencies can make a wide variety of patterns and thereby encode and transmit information. Students also demonstrate their understanding of engineering ideas by presenting information about how.

The crosscutting concepts of cause and effect; systems and system models; stability and change; interdependence of science, engineering, and technology; and influence of engineering, technology, and science on society and the natural world are highlighted as organizing concepts for these disciplinary core ideas. In the PS3 performance expectations, students are expected to demonstrate proficiency in asking questions, using mathematical thinking, engaging in argument from evidence and obtaining, evaluating, and communicating information and to use these practices to demonstrate understanding of the core ideas.
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Assessment does not include quantitative understanding of ionization energy beyond relative trends. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
Examples of particles could include ions, atoms, molecules, and networked materials such as graphite. Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.

Students in high school continue to develop their understanding of the three disciplinary core ideas in the earth and space sciences. The high school performance expectations in the earth and space sciences build on the middle school ideas and skills and allow high school students to explain more in-depth phenomena central not only to the earth and space sciences but to the life and physical sciences as well.
While the performance expectations shown in high school earth and space sciences couple particular practices with specific disciplinary core ideas, instructional decisions should include the use of many practices that lead to the performance expectations. Students examine the processes governing the formation, evolution, and workings of the solar system and universe. Some concepts studied are fundamental to science, such as understanding how the matter of our world formed during the Big Bang and within the cores of stars.
Others concepts are practical, such as understanding how short-term changes in the behavior of our sun directly affect humans. Engineering and technology play a large role here in obtaining and analyzing data that support theories of the formation of the solar system and universe. The crosscutting concepts of patterns, scale, proportion, quantity, energy and matter, and stability and change are called out as organizing concepts for these disciplinary core ideas.
In the ESS1 performance expectations, students are expected to demonstrate proficiency in developing and using models, using mathematical and computational thinking, constructing explanations and designing solutions, engaging in argument, and obtaining, evaluating, and communicating information and using these practices to demonstrate understanding of the core ideas.

Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity. Examples of natural hazards can be from interior processes such as volcanic eruptions and earthquakes , surface processes such as tsunamis, mass wasting, and soil erosion , and severe weather such as hurricanes, floods, and droughts.

Examples of factors that affect human sustainability include agricultural efficiency, levels of conservation, and urban planning. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
Examples for limiting future impacts could range from local efforts such as reducing, reusing, and recycling resources to large-scale geoengineering design solutions such as altering global temperatures by making large changes to the atmosphere or ocean. Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.
An example of the far-reaching impacts from a human activity is how an increase in atmospheric carbon dioxide results in an increase in photosynthetic biomass on land and an increase in ocean acidification, with resulting impacts on sea organism health and marine populations. At the high school level students are expected to engage with major global issues at the interface of science, technology, society, and the environment and to bring to bear the kinds of analytical and strategic thinking that prior training and increased maturity make possible. As in prior levels, these capabilities can be thought of in three stages—defining the problem, developing possible solutions, and improving designs.
Defining the problem at the high school level requires both qualitative and quantitative analyses. While high school students are not expected to solve these challenges, they are expected to begin thinking about them as problems that can be addressed, at least in part, through engineering. Developing possible solutions for major global problems begins by breaking them down into smaller problems that can be tackled with engineering methods. To evaluate potential solutions, students are expected to not only consider a wide range of criteria, but to also recognize that criteria need to be prioritized.
For example, public safety or environmental protection may be more important than cost or even functionality. Decisions on priorities can then guide tradeoff choices. Improving designs at the high school level may involve sophisticated methods, such as using computer simulations to model proposed solutions. Students are expected to use such methods to take into account a range of criteria and constraints, to try to anticipate possible societal and environmental impacts, and to test the validity of their simulations by comparison to the real world. Connections with other science disciplines help high school students develop these capabilities in various contexts.
For example, in the life sciences students are expected to design, evaluate, and refine a solution for reducing human impact on the environment HS-LS and to create or revise a simulation to test solutions for mitigating adverse impacts of human activity on biodiversity HS-LS In the physical sciences students solve problems by applying their engineering capabilities along with their knowledge of conditions for chemical reactions HS-PS , forces during collisions HS-PS , and conversion of energy from one form to another HS-PS These include analyzing major global challenges; quantifying criteria and constraints for solutions; breaking down a complex problem into smaller, more manageable problems; evaluating alternative solutions based on prioritized criteria and tradeoffs; and using computer simulation to model the impact of proposed solutions.
While the performance expectations shown in HS-ETS1 couple particular practices with specific disciplinary core ideas, instructional decisions should include use of many practices that lead to the performance expectations. Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering. Evaluate a solution to a complex real-world problem based on prioritized criteria and tradeoffs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts. Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
