Change Over Time

Overview: To understand a dynamic system, it is essential to be aware of what is changing over time and the pattern of those changes. Using the behavior-over-time graph (BOTG) tool allows you to visually represent the changes that occur over time within a system. This section provides tips for using BOTGs to represent change that occurs within systems in the curriculum and in the organization.

Lesson Objectives

Curriculum Context

Systems Thinking Concepts

Students will be able to:

  • Demonstrate different ways to represent numbers using graphs, sketches, diagrams and manipulatives.

  • Select and use relevant information in the problem to solve it.

Lessons exploring the patterns/trends of change within a system are applicable in any curricular or organizational areas in which dynamic systems are studied or worked within, e.g. mathematics (change in savings account balance), science (change in predator/prey populations), literature (change in a character trait), group dynamics (change in collaboration skills/efforts).

  • dynamic systems

  • pattern and trends

  • change over time

  • temporal boundaries



Systems Thinking Tool(s)
