Children learn about soil layers, plant growth, and the water cycle by building a mini ecosystem. This hands-on experience illustrates how living organisms interact with their environment.
Engaging with real materials allows children to visualize complex environmental processes, reinforcing concepts through embodied cognition. By nurturing their own ecosystem, they see the direct impact of soil, water, and air on plant life.
1. Take a clear glass jar and add a layer of pebbles (1 cm thick) at the bottom. 2. Add a layer of activated charcoal (1 cm thick) on top of the pebbles to filter water. 3. Add a layer of potting soil (2-3 cm thick) for planting. 4. Plant small seeds (like mustard or beans) in the soil, covering them lightly. 5. Water the soil gently until damp, then cover the jar with plastic wrap to create humidity. 6. Place the jar in a sunny spot and observe daily — what changes do you see?
