System, order, organization, and classification Concepts

Primary

System Concepts

  1. Parts are related to a whole.
  2. A whole is related to its parts.
  3. Parts are related to parts.
  4. System is a group of related objects.
  5. Most things are made of parts.
  6. Something may not work if a part is missing.
  7. When parts are put together they can do things they can't do alone.

Order Concepts

  1. Most of the time certain events happen in a similar manner.
  2. Some events are more likely to happen than others.
  3. Some events can be predicted more accurately than others.
  4. Sometimes people aren't sure what will happen because they don't know everything that might be having an effect on the event.
  5. Often a person can find out about a group of things by studying just a few of them.

Organization & classification Concepts

  1. Objects,organisms, events, and systems can be organized in groups with similar properties.
  2. Objects are classified by their common properties.
  3. Classification is one example of organization.

Classification

  1. Objects are classified by there common properties.
  2. Objects are identified by their properties.
  3. Objects have more than one property.
  4. Objects can be ordered by their properties.
  5. Objects in a group share some characteristics while differing in others.
  6. Objects, organisms, events, and systems can be organized into groups with similar properties.

Intermediate

System Concepts

  1. System is a group of related objects that work together for a particular purpose (machines, organism).
  2. The parts in a system interact with the other parts to cause the system to work.
  3. A system may not work if a part is missing, broken, worn out, mismatched, or disconnected.

Order Concepts

  1. Variables affect the order of events.
  2. Order is required to understand the world and predict events.

Organization & classification Concepts

  1. Organization of objects, organisms, events, and systems help people understand similarities and differences that in turn help understand the world.
  2. Classification is one example of organization.

    Classification

    1. Objects are classified by their properties.
    2. A group of objects may be sub classified in one or more ways.
    3. Objects can be classified as either natural or of human design,
    4. System is a group of related objects that work together for a particular purpose (machines, organism). The parts in a system interact with the other parts to cause the system to work.
    5. A system may not work if a part is missing, broken, worn out, mismatched, or disconnected.
    6. Organization of objects, organisms, events, and systems help people understand similarities and differences that in turn help understand the world.
    7. Sometimes thinking about things as systems improves understanding and sometimes it doesn't.

Middle School

System Concepts

  1. System is a group of related objects or components that form a whole.
  2. Can be concrete objects, groups of objects, processes, or ideas.
  3. Some systems have boundaries with input and output of resources and feedback.
  4. Output for one part of a system can be input for another.
  5. Such feedback is used to control the system.
  6. Systems are used as units of investigations.
  7. Thinking about how a system works means observing and collecting date on each part and how each part interacts with the others.
  8. Systems can be connected to other systems and thought of as a subsystem.
  9. Systmes may have what appear to be natural boundaries, but are generally arbitrary.
  10. System ideas are used outside of science. Technolog and business use system analysis which looks at systems relationships by their inputs and outputs. Computer programming use these ideas with procedural languages, functions, and object oriented programming.

Order Concepts

  1. Probability is the relative certainty or uncertainty that people assign to events happening or not happening in a certain place or time.
  2. Creating knowledge through observation of different variables influence on objects, organisms, populations, communities, and events helps create better explanatory models

Organization & classification Concepts

  1. Organizations such as the periodic table, classification of animals, properties of matter, cells, tissues, organs, organisms, populations, communities, and ecosystems have helped in developing explanations about these objects and their interactions.
  2. Classification is one example of organization.

Classification

  1. Objects and events can be classified as members of an ascending hierarchy.
  2. A system can include processes as well as things.
  3. Thinking about things as systems means looking at how every part relates to others.
  4. Sometimes objects have properties of two different groups and it's difficult to decide in which group to put them.
