This learning resource focuses on the journey of carbon through the environment, explaining the concepts of carbon sources and sinks. By exploring how carbon is released into the atmosphere through various processes (like respiration and combustion) and how it is absorbed and stored in places like oceans and forests, learners will grasp the dynamic balance of the carbon cycle. Activities encourage students to distinguish between sources and sinks, understand their roles in the carbon pathway, and consider the impact of human activities on this balance. The document also emphasizes the importance of both short-term and long-term carbon storage.
