This video looks at the global population and trends. It also explains the concept of carrying capacity and how a person's behavior influences carrying capacity. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video describes the ecological footprint and its limitation. It goes into some depth on the computation on the footprint and what it means for the global population. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation.

Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar to what is called carrying capacity, the maximum population size that an environment can normally sustain), the initial organism gestation rate, and the availability of resources. How systems function often depends on many different factors. By altering these factors one at a time, and observing the results, students are able to clearly see the effect of each one.

This activity is a simulation that illustrates how population sizes are affected by predator-prey relationships and competitive interactions among prey.

In this lesson, students learn how adaptations, limiting factors, and predator prey relationships all affect the survival of plants and animals. Predator-prey relationships are simulated in two games, where students record their experiences and display data in story and chart/graph form, and explore the adaptations of animals in terrestrial and aquatic habitats. Extension activities include habitat investigations in natural areas.

This is an example lesson plan with materials about the China's enviornmental issues for educators to use for creating their lesson. This lesson plan has multiple activities, readings, and pictures about various enviornmental issues that are occuring in Chhina in current times.

This video looks at the meaning of sustainable development and why the current best practices prescribe participatory methods. It also presents a visual model for sustainable development that is closer to the physical reality than the "triple bottom line" model of environmental, equity, and economic goals. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video explores the meaning of sustainable development from a biomimicry view. It is largely based on the work of CS Holling and associates. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation.

This video considers a model of human impact proposed by Ehrlich and Holdren called the "IPAT" equation. It reveals its underlying assumptions and the additional opportunities for reducing impact.

Introduction to the concept of a dynamic system. Includes discussion of system and surroundings and system boundaries. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation.

This video explains thermodynamic systems, open and closed systems, and the four key properties of a system. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation.

This video looks at the cause of system behavior as being like an iceberg. This idea was proposed by Peter Senge in his book, "The Fifth Discipline" (1990), Doubleday Publishers. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives, Assessment, and Activities.

This video explains Aristotle's model of causality and how it can be used to gain insight into systemic behavior. Many of the ideas presented in this video have been contributed by Roger Burton. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives, Assessment, and Activities.

This video, based on ideas of Donella Meadows (Thinking in Systems: A Primer | 2008, Chelsea Green Publishing), describes different types of interventions that are possible in a system and their potential leverage.

This video is an introduction to the global issue of water. It examines questions like "How can there be a water shortage when we are surrounded by water?". This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video looks at how water is provided for our use through the hydrologic cycle. It also explains how global climate change disturbs the storage of water in the various global compartments. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

How do we account for water use? What is the difference between water consumed and water withdrawn? What is the water footprint tool? This video examines these questions. This video is part of the Sustainability Learning Suites, made possible in part by a grant from the National Science Foundation. See 'Learn more about this resource' for Learning Objectives and Activities.

This video looks at how water use and energy use are connected when industrial era technologies are used as the primary means of supplying process energy.
