Performance Expectations ? About
The NGSS Performance Expectations are statements that explain what all students should
know and be able to do after instruction. These comprehensive statements should not
limit teaching and learning. Performance Expectations are best addressed in instruction
when resources are bundled together to address big ideas in science. The CLEAN collection
includes resources that do not fully address any one Performance Expectation. Bundling
CLEAN resources will support instruction towards Performance Expectations. Most
resources are tagged for DCIs, SEPs, and CCCs. Those tagged for Performance Expectations,
fully address the PEs.

Evaluate solutions for using energy and mineral resources.
Evaluate a technological solution that reduces human impacts on natural systems.
Design a solution to a complex problem by breaking it down into smaller problems that can be solved through engineering
Evaluate a solution based on priorities and trade-offs
Disciplinary Core Ideas
Humanity faces global challenges, such as the need for supplies of clean water and food, or for energy sources that minimize pollution. These can be addressed through engineering.
When evaluating solutions, one should consider cost, safety, reliability, aesthetics, and social, cultural and environmental impacts.
Resource availability has guided the development of human society.
ll forms of energy production have costs, risks, and benefits. New technologies and regulations can change these factors.
Science and Engineering Practices
Analyze data using tools, technologies, or models, in order to make scientific claims or determine solutions.
Analyze data to identify features of a proposed process or system in order to optimize it.
Design, evaluate, or refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, and other criteria.
Communicate scientific or technical ideas in multiple formats.
Cross Cutting Concepts
Patterns of performance of designed systems can be analyzed and interpreted to improve the system.
Cause and effect relationships can be predicted by examining what is known about smaller scale mechanisms.
Changes of energy and matter into, out of, and within systems can be described.
