Commodities are a class of goods that can be produced in such a way that it is difficult or impossible to distinguish one instance of the commodity from another. The price of the commodity is determined as a function of the market as a whole, not in regard to who produced it or how it was produced. Commodities share a common problem in that prices and production exhibit repeating cycles. This simulation introduces students to the concept of commodity cycles by comparing two types of hog
farms:
• Large; over 2000 hogs produced per year and primarily serving the price-conscience consumer
• Small; fewer than 2000 hogs per year and primarily serving the quality-conscience consumer.
Complex Systems Connection: Cause within System. Five interdisciplinary areas are covered in a series of lessons, utilizing a family of models that all generate oscillation. Oscillation in real-world systems is often considered problematic rather than a consequence of system structure. This progression of lessons will help students understand that undesirable behavior can be a consequence of system structure and not a result of outside, uncontrollable influences. In other words, a system that oscillates does so because it has an inherent tendency to do so. |

This lesson explores a commodity market, hog farming, periods
from two different perspectives. Students experience a simulated large and small farm, comparing the similarities and differences among trends, including retail pork prices and availability of pork.

This model illustrates how a commodity often oscillates over time based on supply, demand, and price. Students explore a pork commodity, comparing simulation results given two scenarios for large and small farms.

Led by a partnership between MIT Professor Emeritus Jay W. Forrester and the Creative Learning Exchange, the goal of the Characteristics of Complex Systems Project is to create online curricula for ages five and above that will illustrate the characteristics of complex systems. In exploring the nature of complex social systems, the curricula address questions such as – why do such systems resist policy changes? Why are short-term and long-term responses to corrective action often at odds with each other? How can leverage points be applied to bring about desirable change in social systems?
The goals of the project are grounded in the belief that an abstract level of understanding of social systems will help prepare future citizens to actively shape their society.
The lessons and simulations are based upon the fourth characteristic of complex systems: the cause of the problem is within the system.

In this activity, students use feedback loops to discover how the skeletal system helps the body maintain balance in blood calcium levels. Students then make connections to the causes and treatments of the bone disease osteoporosis.
This activity was used in a high school Anatomy and Physiology course within a unit on the skeletal system. |

Follow me through my first years’ journey in Systems Thinking. Education can be a powerful means for initiating or reaffirming a person’s sense of responsibility for the environment. To get my students outside and interacting with the beauty that exists around us is a priority in changing their perspectives and can lead to an increased understanding of stewardship and ecosystem sustainability. Connecting the intrinsic human relationship within our youth with nature is complex, but includes establishing the Systems Thinking framework into the observation of natural events as a routine exercise. Harnessing students’ desires to be involved in digital technologies while getting them outdoors leads to new potential. Technology will be our leverage to enable students to participate in social networks and informal learning environments that will encourage new participation in science across the curriculum.

The Population Dynamics series are designed to supplement existing high school history curricula and be largely self-directed by students outside of class time. The lessons are intended to introduce students to a variety of systems tools (behavior-over-time graphs, stock/flow maps, models/simulations) alongside primary and secondary historical resources. Part A focuses on the impact of population on the settlement of New England (1630).
Complex Systems Connection: Separate Cause and Effect. The interactions of population dynamics with changes in the environment and social systems of a nation play out over time. The story of American settlement is not complete without understanding the conditions people in England experienced before deciding to cross an ocean to a new land.
Cause within System. This systems view is organized around three sectors: population dynamics, environmental factors, and changing social systems. Their interactions in England during colonial times contributed to Puritan emigration to New England. |

Complex Systems Connection: Separate Cause and Effect. Population dynamics and changes in the environment and social systems of a nation play out over time. Generations of Americans, together with streams of immigrants, had children and grandchildren, all needing space to lives. Our nation's population grew (and is still growing today due to the same forces). The settlement of America is a story about population growth and migration.

The Population Dynamics series are designed to supplement existing high school history curricula and be largely self-directed by students outside of class time. The lessons are intended to introduce students to a variety of systems tools (behavior-over-time graphs, stock/flow maps, models/simulations) alongside primary and secondary historical resources. Part C focuses on U.S. urbanization between 1820 to 1920.
Complex Systems Connection: Separate Cause and Effect. The process of urbanization unfolds over decades, sometimes centuries. Small changes in society (inventions of labor-saving devices for farming) accumulate over time and cause other changes (people move to cities to find jobs). The trend can be imperceptible over a few years but becomes apparent when looking at a long timescale. Urbanization features push and pull forces that transform entire nations. Changing population dynamics, environments and social systems push some people to seek opportunities elsewhere. The result can be explosive urban growth that creates a pull for others.
Short and Long Term Conflicts. Achieving an immediate goal (welcoming new labor, improving labor productivity) can come at long-term costs (lower wages for all, fewer jobs). Complex systems often feature such tradeoffs - seemingly rational decisions and actions in the present can have unintended consequences in the future. |
