Core Skills Analysis
Science
The students assembled a closed terrarium, layering soil, charcoal, and plants while measuring moisture levels and recording observations. They identified the roles of producers, consumers, and decomposers within the miniature ecosystem they created. By monitoring light exposure and water cycles over the 80‑minute session, they explained how photosynthesis and transpiration sustain life inside the terrarium. They also reflected on how sealed environments model real‑world ecosystems and the importance of balance among biotic and abiotic factors.
Tips
Extend learning by having students design a hypothesis about how changing one variable—such as light intensity or water amount—will affect plant growth, then test it over a week and chart results. Incorporate a digital scavenger hunt where learners locate real‑world examples of similar closed ecosystems, like bottle gardens or greenhouse systems, and compare their conditions. Invite a local botanist or ecologist for a virtual Q&A to deepen understanding of ecosystem interdependence and conservation. Finally, encourage students to write a short “ecosystem journal” documenting daily observations, challenges, and successes in maintaining their terrarium.
