Model Mysteries: An Exploration of Vampires, Zombies, and Other Fantastic Scenarios to Make the World a Better Place
Author(s): Anne LaVigne, & Lees Stuntz Subject: Cross-Curricular
  This book contains six main chapters, each with a new mystery to solve. Each chapter has a number of similar stories to try, depending on your interest. The modeling activities are intended for students from ages 10 to 110. In other words, if you’re interested in thinking about how to solve mysteries and like the idea of creating computer models and applying them to real-world problems, this book is for you. You can use it independently as a student, work with a group of students, or if you’re a teacher, share it with interested students to complete a guided or independent study project. In addition to the main chapters, Chapter 7 provides an extension to build additional capacity in modeling, and Chapter 8 includes next steps, additional resources, and information about modeling software. You can also reference the appendices for details about completing the chapter mysteries.
 
Modeling Air-Powered Rockets
Author(s): Christopher DiCarlo Subject: Science
  Students learn the physics of forces acting on a paper rocket in the context of systems thinking and modeling tools in this project. The lessons become more authentic and engaging when the classroom moves outside.

Modeling Dynamic Systems Section 10
Author(s): Diana Fisher Subject: System Dynamics
  There are several characteristics of complex systems that can be discussed with students during these lessons. The fictitious city seems to face a dilemma; the tanning industry provides needed jobs in the present, but water pollution can cause serious detrimental effects over the long term. This is closely coupled with the idea that cause and effect in complex systems are often separated by time and space. In the case of pollution, contamination can take decades to produce measurable effects. In the meantime, the range of impact can spread far from the initial source via transport in water, wind, etc. Finally, the lesson mentions that tanning has been outsourced from this country to developing countries; a classic case of "shifting the burden." Rather than allowing the true costs of tanning to be reflected in the prices of the finished goods, the industry itself escapes pressure to reform by sending the negative consequences to other, less regulated countries.

Modeling Dynamic Systems Section 6
Author(s): Diana Fisher Subject: System Dynamics
  In the classroom example provided in this section, the author lists many "potential systems problems" that are related to the issue of overpopulation. As an extension exercise, students can be asked to identify ways in which people have attempted to solve these related problems. Did the solutions address the underlying population issue in any way? Were they successful interventions? In complex systems, proposed solutions that do not recognize and address the underlying dynamics that need to be changed are low-leverage policies; they usually fail to achieve any significant change in the overall behavior of the system. Students can be asked to undertake a similar analysis in their own investigation of a news story.

Modeling Dynamic Systems Section 7
Author(s): Diana Fisher Subject: System Dynamics
  The dynamics of epidemics can be used to impart an intuitive understanding of what it means to say a policy has "high leverage." Students can be tasked with conducting policy analysis to determine the leverage points in preventing an infectious illness from becoming an epidemic. Along the way they will learn why well-intensioned but low-leverage policies in real life often fail to have the desired effects in complex systems. For some illness/disease, symptoms appear long after initial infection. Sometimes people travel great distance while infected because they are unaware of the infection. Medical "detectives" faced with an epidemic must understand how the infection spreads and how quickly. Delays in the system make this more difficult.

Modeling Dynamic Systems Section 8
Author(s): Diana Fisher Subject: System Dynamics
  Policy analysis gives students an opportunity to learn first-hand that complex systems are rich in feedback. They will experience the frustration of implementing well-meaning interventions, only to have them defeated by the feedback mechanisms of the system itself. They will learn why some policies have more leverage than others, and why those policies are often the most difficult to implement correctly in real life.

Modeling Dynamic Systems Section 9
Author(s): Diana Fisher Subject: System Dynamics
  Supply chain dynamics are useful for illustrating the complex system characteristic that cause and effect are often separated by both time and space. Supply chains are often global, with decisions taken today causing impacts into the future and across national boundaries. The lessons of this section can also be used in conjunction with the Oscillations curriculum, particularly the lesson on commodity cycles, to illustate that the cause of a problem is within the system.

Modeling Physics: System Dynamics in Physics Education
Author(s): Horst P. Schecker Subject: Science
  System Dynamics modeling helps to shift the focus of physics instruction towards more qualitative learning. Dynamic modeling requires students to analyze a phenomenon and develop the model, whereby they are introduced into the strategy of expert problem-solvers, i.e. to concentrate on a conceptual and semi-quantitative analysis. The modeling system supports the learner both in constructing the model and exploring its physical adequacy through simulation runs. Lead article in Spring 1996 CLExchange newsletter.

Models For Use with At-Risk Students
Author(s): Ron Zaraza Subject: Cross-Curricular
  From CC-STADUS. Six models, accompanied by student work packets, which cover a variety of topics that are either difficult for many students to grasp, or are not usually taught to students identified as At-Risk. The six models are: Basic Coordinate Graphing; The Bathtub: Adventures in Linear Graphs; Changing Slopes; Parabolic Graphs; Exploring Feedback: Reservoir Control; and Population Growth and Renewable Resources. Not designed exclusively for use with identified At-Risk students.

Oscillations 1 Background Information on Simulation Created for Lesson 1: Springs Everywhere: Exploring Spring-Mass Dynamics
Author(s): Anne LaVigne, Jennifer Andersen, & in collaboration with the CLE Subject: Cross-Curricular
  This lesson is a precursor to the Oscillation curriculum created for the Complex Systems Project. Experimenting with a virtual spring will help students gain an intuitive understanding for why a spring oscillates. This knowledge will be reinforced in other lessons in this series.

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.
