Science Standards and Progress Indicators
Standard
5.1
All students 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 systems 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 the 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 loops 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.
