In this video, a PhD Student from the University of Maine explains how ice cores are used to study global climate change.

This unit introduces systems and systems thinking. The unit is easily adaptable to any course and includes an introduction of terminology, motivation for using systems thinking, and practice reading, as well as interpreting and evaluating systems diagrams. Note that an Internet connection and speakers are required to play the audio file in Part 3.

This unit includes an opportunity for students to move from definitions into reading and creating a diagram of a complex system relevant to their course, and then to exploring the connections between the components in the system. An exercise is provided to help students identify complex systems and their component parts from the world around them. Students will draw and revise a systems diagram, including identifying measurable quantities in the system, and participate in a gallery walk. The unit ends with students constructing a system diagram from photographs they take, and reflecting on their process. Note that to carry out the activities described in this unit, groups of students will need large sheets of paper and markers, or whiteboard/chalkboard space, to create a diagram.

This unit introduces systems modeling, which allows students to quantify and manipulate system components to create system responses. Students use a simple systems model of a bathtub to explore the effect of flow rates on system equilibrium. To complete the unit, students will need a method for creating and sharing diagrams (whiteboards, posters, etc.), and will ideally have access to free systems modeling software.

Feedbacks are a critical part of many systems. In this unit, students use a systems model to explore the effect of positive (reinforcing) and negative (balancing) feedbacks on system behavior. Model results are then used as a basis for interpreting Arctic sea ice data. To complete the unit, students will ideally have access to free systems modeling software.

This unit has students build on a system diagram, to include new knowledge about quantitative values and relationships. They will also write about and discuss what they know about their systems, the questions that still remain, and how to find answers to their questions.

This in-class exercise is an alternative to standard review sessions and models the systems thinking students need to do when working on complex, interdisciplinary issues. Students quiz each other on course material and then find authentic (and often creative) connections between seemingly disparate topics in the course. This approach challenges students to use holistic thinking when reviewing, and can be readily customized for any course.
