Earth is unique within our solar system and this innovative activity teaches students about the four "spheres" that are essential to maintaining our world. After listening to a poem about the interconnections beween our atmosphere, hydrosphere, lithosphere and biosphere, learners go outside to find evidence of each system. From quietly observing organisms in natural habitats to feeling the soil between their fingers, pupils describe their observations while considering how abiotic and biotic features interact to support the living world. This outdoor experience fosters a closer relationship to nature while reinforcing an understanding of why humans must always consider how our actions impact the air, water and land that are essential to life on our planet.
This activity supports Grade 4-9 Science learning related to energy flow and connections within biomes and ecosystems and how non-living habitat features such as water affect biodiversity. Students will also be able to define and describe atmosphere, hydrosphere, lithosphere and biosphere. The outdoor experience fosters a stewardship ethic as learners develop a deeper awareness of the relationship between human activity and environmental health.
This learning experience could develop into an Earth Day action project where a class works with local volunteers to establish a short nature trail on school grounds. A student-produced guide that identifies flora and fauna found along the path would support its use by teachers, students and community members.
