Stability and Change TEKS


5.G Describe how factors or conditions can cause objects, organisms, and systems to either change or stay the same


5.G Explain how factors or conditions impact stability and change in objects, organisms, and systems


5.G Analyze and explain how factors or conditions impact stability and change in objects, organisms, and systems

The concepts of stability and change are crosscutting scientific principles that help scientists understand the behavior and dynamics of systems over time. These concepts recognize that systems can exhibit both stable patterns and undergo changes or transformations. They are fundamental in various scientific disciplines, from physics and chemistry to biology and ecology.


- refers to the state of a system or phenomenon that remains relatively constant or unchanged over time, even in the presence of external influences or disturbances. Stable systems exhibit patterns, structures, or behaviors that persist or return to a balanced state. Stability is essential for understanding the resilience, equilibrium, and regularity of natural and human-made systems.


- refers to the process or occurrence of alteration, transformation, or variation in a system or phenomenon over time. Change can occur at different rates, scales, and intensities. It is through the study of change that scientists gain insights into the dynamics, evolution, and adaptation of systems.

Understanding the interplay between stability and change is essential in scientific inquiry. While stability allows for the identification of patterns, predictability, and equilibrium, change provides insights into the mechanisms, forces, and factors that drive adaptation and system dynamics. Both concepts are intertwined and provide a holistic perspective on the behavior of systems.

Scientists study stability and change to understand how systems respond to internal and external influences, how they adapt to changing conditions, and how they maintain or shift their state over time. These concepts are applicable across scientific disciplines, including physics, chemistry, biology, ecology, and social sciences, helping to unravel the complexity and dynamics of natural and human-made systems.
