This learning resource focuses on the connection between animals and plants through the process of atmospheric exchange. It begins with a practical activity where students experience the physical sensations of their own breath, noting temperature, moisture, and force as they exhale. The resource encourages students to reflect on how their exhaled air interacts with the biological environment, particularly plants. A section is dedicated to visualizing the gas exchange loop, where students model the movement of gases from animals to plants. It concludes with a conceptual analysis where students articulate how plants benefit from the gases released by animals, using the concept of an 'atmospheric loop.' This resource aims to deepen understanding of ecological interactions and the importance of this exchange for plant growth.
