Climate Interactive has many tools that can be used in classrooms from middle school to graduate-level for interactive and engaging classes on topics like, climate change, energy policy, and systems thinking. 
World Climate Exercise:
World Climate is a role-playing climate simulation that gives groups from 6-80 a chance to experience how to negotiate a global agreement to mitigate climate change. The group breaks into teams that represent different parts of the world and then form proposals to limit climate change to 2 degrees, which are then tested with either the C-ROADS or C-Learn simulations. This is a great way to have groups explore the implications of climate change and the level of response needed to address it. Materials to facilitate the World Climate Exercise are available in several languages here.
C-Learn:
C-Learn is a simulation that helps people to understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various actions like, reducing fossil fuel emissions, reducing deforestation, and planting trees. It is specifically designed for climate communicators, educators, and leaders of the World Climate Exercise, who want to use a web-based simulation to improve understanding of large-scale actions to mitigate climate change. C-Learn can be found here.
