Earth's Systems

Students introduce their locality and themselves to the partner class, then brainstorm what the atmosphere, hydrosphere, geosphere, and biosphere look like around them.

In small groups, students survey and map the atmosphere, hydrosphere, geosphere, and biosphere in their neighbourhood, using photos, local data, and observations. They then draw the links they see between the spheres.

Students investigate specific local interactions, such as how rain affects soil or how plants shape air quality, and record evidence for each connection. They prepare questions to compare with the partner class.

Both classes share their maps during a live video call and compare how each sees the connections between the spheres. Students discuss similarities and differences across regions and take notes on what surprises them.

Students use a shared forum to analyse why their perspectives differ, referring to local culture, climate, and land use. They run a short survey on how each community views these connections and summarise the findings.

Students present their revised maps and the key insights they gained from the exchange to both classes. They end with a reflection on how intercultural perspectives changed their understanding of the spheres.
