Build a Mini Ecosystem (Terrarium) - 15/12/2025 19:35 EST

Science Project: Creating and Observing a Mini Ecosystem (Terrarium) 1. Background Living organisms interact with their environment to form an ecosystem. To understand the relationship between plants, soil, water, and air, direct observation through a mini ecosystem is needed. 2. Objectives To identify biotic and abiotic components in an ecosystem To observe plant growth To understand the balance of a simple ecosystem 3. Tools and Materials A clear used plastic bottle Humus soil Small pebbles Small plants (moss/grass) Water as needed Scissors 4. Procedures 1. Cut the plastic bottle into two parts. 2. Put small pebbles at the bottom as the base layer. 3. Add humus soil on top of the pebbles. 4. Plant the small plants into the soil. 5. Water lightly. 6. Close the bottle and place it in a bright area. 5. Observation Results The plants stayed alive and grew Water evaporation occurred inside the bottle The mini ecosystem survived for several days 6. Conclusion The mini ecosystem shows that living organisms need water, soil, and light to survive. Ecosystem balance is very important for plant growth. 7. Benefits of the Project Improves observation skills Encourages environmental awareness Helps understand ecosystem concepts directly
