By rolling a die, students will simulate a molecule of carbon’s movement with in the carbon cycle. This is a fun, active way to introduce students to the carbon cycle and/or to review the cycle and identify carbon sinks and sources.
Students experience the carbon cycle as CO2 molecules or as stored carbon and travel the path of
How glaciers in the polar regions respond to continued climate warming is of great concern. Changes in overall glacier velocities and calving dynamics have immediate impacts on sea level. Accurate predictions of how and when ice loss will occur are crucial to forecasting future environmental change.
This lesson results from experiences working in and around Kronebreen glacier in

The report is written by teacher participants upon return from their field expedition portion of the PolarTREC program. It summarizes the benefit of the expedition to the teacher, a description of activities, and a summary of how teachers plan to link this experience in classrooms and communities. This is a public document that will be posted in teacher portfolios and
