 FIRST OF TOP WORDS OF THE COMP 40 SYSTEM OPENED AND CLOSED OPENED OR CLOSED SECOND GROUP OF 3 OF COMP 40 CHANGE CONSTANCY CHANGE, CONSTANCY LAST OF THE COMP 40 MODEL MODEL-PHYSICAL, MATHMATICAL CONCEPTUAL (ABSTRACT MODEL) PHYSICAL, MATHMATICAL, CONCEPTUAL THE TEACHER COMPREHENDS WHAT? THAT ALL BRANCHES OF SCIENCE ARE CONNECTED BY UNIFYING CONCEPTS AND PROCESSES SYSTEMS PART 1 DEFINE A SYSTEM A SYSTEM IS A GROUP OF OBJECTS OR ENTITIES CREATING A WHOLE IN WHICH EACH ELEMENT INTERACTS WITH OR IS RELATED TO ANOTHER OBJECT SYSTEMS PART 2-SUBSYSTEMS SUBYSTEM EXIST, WITHIN THE LARGER SYSTEM SYSTEMS PART 3-ALL ELEMENTS OF A SYSTEM ARE IMPORTANT FOR THE CORRECT FUNCTIONING OF THE SYSTEM; IF A PART OF A SYSTEM CEASES TO FUNCTION, THEN THE ENTIRE SYSTEM SUFFERS AND EITHER STOPS WORKING COMPLETELO OR FUNCTINS INCORRECTLY B SYSTEMS CAN BE SIMPLE OR COMPLEX-opended !) THEY HAVE BASIC PROPERITES THAT CAN BE DESCRIBED I N TERMS OF SPACE, TIME, ENERGY, AND MATTER, AND THEY ARE SUBJECT TO CYCLES, STRUCTURES AND PROCESSES B SYSTEMS CAN BE SIMPLE OR COMPLEX-closed 2) PATTERNS PRESENT THEMSELVES IN SYSTEMS IN THE FORM OF CHANGE AND CONSTANCY B SYSTEMS CAN BE SIMPLE OR COMPLEX-Dynanic systems 3) THIS PATTERNS CAN BE OBSERVED IN ORDER TO USE THEM AS PREDICTIVE TOOLS Hint: THE FOLLOWING ARE SUBJECT TO CYCLES, STRUCTURES, AND PROCESSES Dynamic open systems Open: an open system is capable of exchanging matter, energy or information with its surrounding environment open closed systems CLOSED A closed system is not capable of exchanging matter, energy or information with the outside environment and so is self-contained. Outside events have no influence on what occurs in this system is destined to stop after a period of time. closed dyanmic system Dynamic system: Systems that have variable relations with their surroundings Some examples of systems include variable relations A) Natural systems- A) Natural systems-These include things such as the ecosystem, the solar system, the water cycle, and living organisms. ecosystem such as the water cycle and living organisms B) Human-made systems- B) Human-made systems-As the name implies, these are systems that are man mad, such as the machine. systems that man made like a machine C) Physical-or THERMOdynamic systems-these systems are based solely on matter and energy C) Physical-or THERMOdynamic systems-these systems are based solely on matter and energy soley on matter and energy D) Living systems- D) Living systems-this type of system can be either part of (such as gene networks) or a whole living organism, members of a group of organisms tht interact with other members of a group of organisms that interact with other members, or groups of organisms that interact with other groups. Living systems are types of natural systems. organizms that intreact with other groups Models discussed Scientists need to refer to models in order to understand systems, a model is a representation or description of something, specifically one that can be used to make predictions that can be tested by experiemtn or observation defination of a modol Models discussed Often the representation has been constructed from a particlular point a particular viewpiont Order to address some speicific , desire of the investigator, and for this one must always be careful in choosing which model and what exactly needs to be studied Order to address some speicific , of the investigator, and for this one must always be careful in choosing which model and what exactly needs to be studied researchers need to be sensitive of what modols they choose Models can be used in what three ways Physcial Models Mathmatical models Abstract (conceptual Model) Physical mode math models abctract-theoritical models Defination of an abstract model is a what? A therotical construct that represents something, with variables among which there is a set of locgial relationships therotical construct Three Kinds fo enabling easoing with a framework of logical, idealized of models have the purpose of the formulation enabing reasoning within a framework of logical, idealized cconcepts that allow the formulation of soluology, anong other tions Indeed, abstract models are used for discovering ne facts for evaluating hypotheses, for devising experimental procedurs more theory of abstract models Models especially abstract ones, can be used to construct ccomputer simulations tha can display teh behavior of a system over time, Simulations can be used to unravel trrends and consequences following changes of variables in ecomomics, biology, ecology, and m eteorolgy, among other areas THOUGH SCIENTIFIC ENDEAVORS ARE DIVIDED INTO DIFFRENT BRANCHES LIKE A TREE, SUCH AS THE CHEMISTRY BRANCH, AND BIOLOGY BRANCH THE TEACHER MUST REALIZE THAT THERE ARE PRINCIPLES AND PROCESSES THAT UNITE TEHSE BRANCHES the tree POSSIBLY THE MOST IMPORTANT CONCEPT IS THAT: OF THE SYSTEM, WHICH ENCLOSES A SET OF GENERAL CHARATERISTICS APPLICABLE TO ALL SCIENTIFIC DISPLINES WHICH ENCLOSES A SET OF GENERAL CHARATERISTICS APPLICABLE TO ALL SCIENTIFIC DISPLINES What ever part of the science tree is being studied, the teacher must know that models are useful tools in studying and understanding systems, teh teacher should be familiar with and know how to use some of the more common models Models should be used for most systems
