Oscillations 7C: Hog Wild: Fluctuations in Commodities Markets
Author(s): Anne LaVigne, Jennifer Andersen, & in collaboration with the Creative Learning Exchange Subject: Cross-Curricular
  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.

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.

Oscillations: Characteristics of Complex Systems in K-12 Education Project
Author(s): Jennifer Andersen, Anne LaVigne, & in collaboration with the CLE Subject: Cross-Curricular
  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.

Population Dynamics, Part A: Connecting Past, Present and Future, Part A:Push and Pull Forces in Settling America
Author(s): Jeffrey Potash, & Jennifer Andersen Subject: Cross-Curricular
  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.

Population Dynamics, Part B: Connecting Past, Present and Future, Part B:Push and Pull Forces in U.S. Colonial History
Author(s): Jeffrey Potash, & Jennifer Andersen Subject: Cross-Curricular
  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 B focuses on population change in New England in Colonial times and how it contributed to the growth of America.

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. Cause within System. This systems view is organized around three sectors:population dynamics, environmental factors and changing social systems. Their interactions in New England during colonial times contributed to the settlement of America.

Population Dynamics, Part D: Connecting Past, Present and Future, Part D:America's Baby Boom and Global Youth Bulges
Author(s): Jeffrey Potash, & Jennifer Andersen Subject: Cross-Curricular
  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 D focuses on America's baby boom and global youth bulges.

Complex Systems Connection: Separate Cause and Effect. Baby booms and youth bulges play out over time. The impacts of population dynamics may cause changes to the environment and social systems that will be felt over several generations. It is difficult to predict the effects of issues that are decades away, and even harder to implement policies that will correct for them. Baby booms and youth bulges can create push factors that cause particular age groups to migrate to new countries. Young or old, people respond to shrinking opportunities by looking outside national borders. One country's youth bulge may become another region's immigration influx. Cause within System. The decision to have a child is very personal, but common factors are often present (age, finances). These factors also affect the rate at which people die, leave (emigrate) or come to a new area (immigrate). This demographic system generates its own behavior. The particular trajectory of population growth or decline is a consequence of these various flows of people. Shifting Burden. Humanitarian aid is widely provided to nations in need. When aid creates a dependence between the giver and receiver, the ability of the receiving country to meet its own needs may be compromised. Over time the "burden" of providing for a country's citizens may be transferred to the intervener - the country or countries providing the aid.

Shape of Change (Lesson 6): The Tree Game, including Stocks and Flows
Author(s): Rob Quaden, Alan Ticotsky, & Debra Lyneis Subject: Cross-Curricular
  From "The Shape of Change." Students explore what happens to the number of trees in a forest over time as a forester plants and harvests each year. With the included Stocks and Flows lesson, they gain experience anticipating and observing how a stock changes with different inflow and outflow rates.

Complex Systems Connection: Cause within System, Short and Long Term Conflicts. People sometimes decide to use natural resources to meet present goals (satisfy customers, increase profits) and ignore long-term consequences. In systems where renewable resources are used up, people often blame others. Decisions to use the resource faster than it can be replenished is the real cause, however.

Shape of Change (Lesson 7): The Tree Game Puzzle, including Stocks and Flows
Author(s): Rob Quaden, Alan Ticotsky, & Debra Lyneis Subject: Cross-Curricular
  From "The Shape of Change." This puzzle is an extension of the Tree Game. After playing the Tree Game, students explore what happens to the number of trees in a forest following a variety of planting and harvesting policies. In the Stocks and Flows lesson, students begin to learn to clarify their thinking, and experience the power of making stock/flow maps.
