Modeling in 9–12 builds on K–8 and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed worlds.

• Develop a model based on evidence to illustrate the relationships between systems or between components of a system.
• Use a model to predict the relationships between systems or between components of a system.
• Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
• Use a model based on evidence to illustrate the relationships between systems or between components of a system.
• Use a model to provide mechanistic accounts of phenomena.
