Modeling in 6–8 builds on K–5 and progresses to developing, using and revising models to describe, test, and predict more abstract phenomena and design systems.

• Develop a model to predict and/or describe phenomena.
• Develop a model to describe unobservable mechanisms.
• Develop and use a model to describe phenomena.
• Develop a model to describe phenomena.
• Develop a model to generate data to test ideas about designed systems, including those representing inputs and outputs.
