Science Standards And Progress Indicators
Standard 5.1:
All Students Will Learn To Identify Systems Of Interacting Components And Understand How Their Interactions Combine To Produce The Overall Behavior Of The System

Descriptive Statement: The natural world and the world built by humans both provide examples of systems where interacting parts work together as a whole. This standard asks students to analyze, understand, and design systems of integrating parts

Cumulative Progress Indicators

By the end of Grade 4, students:


Recognize that most things are made of components that, when assembled, can do things they could not do separately.


Recognize that since the components of a system usually influence one another, a system may not work if a component is missing.


Diagram the components of a system.

Building upon knowledge and skills gained in the preceding grades, by the end of Grade 8, students:


Describe components of a system and how they influence one another.


Recognize that most systems are components of larger systems and that the output of one component can become the input to other components.


Disassemble and reassemble the components of a system, analyzing how they interact with each other.

Building upon knowledge and skills gained in the preceding grades, by the end of Grade 12, students:


Recognize that the behavior of a system may be different from the behavior of its components.


Explain how feedback can be used to control the behavior of a system.


Identify and diagram feedback loops that occur in biological or ecological systems.


Identify and diagram feedback loops designed for common control systems, such as home light switches and thermostats.
