Unifying processes in science are the broad concepts that connect scientific ideas across disciplines (life, earth, and physical sciences). These concepts help students recognize how different science topics are part of an organized system and not isolated facts. By understanding systems, order, and organization, students build a framework for reasoning, analyzing, and applying science across real-world contexts.
1. Systems
A system in science is made up of individual parts that work together as a unit. When one part of the system changes, it can impact the entire system. Understanding systems helps students analyze how processes are organized and how parts are interdependent.
Key ideas about systems:
- Systems are made of components (parts), each with a specific function.
- The interconnectedness of parts means a change in one affects the others.
- Systems have boundaries, which define what’s included.
- Systems receive inputs (what goes in) and produce outputs (what comes out).
- Systems operate at various scales: microscopic (cell) to cosmic (solar system).
