Scientists and Engineers at Work The Next Generation Science Standards (NGSS) focuses on three distinct and equally important dimensions to learning science. These dimensions are combined to form each standard -or performance expectation-and each dimension works with the other to help students build a cohesive understanding of science over time. CROSSCUTTING CONCEPTS: Helps students explore connections with Physical Science, Life Science, Earth and Space Science, and Engineering Design.
DISCIPLINARY CORE IDEAS: The key ideas that have a broad importance within or across multiple science or engineering disciplines.
PRACTICES: Describes behaviors that scientists engage in as they investigate and build models and systems. Fifth Grade focuses on matter, energy, motion, structures, Earth's systems, and engineering design.
