Crafting Mini Ecosystems: 7th std Terrarium Project
Purpose: Visualizing the Water Cycle
In a fusion of creativity and science, Grade 7 students at Vidhya Peetham i-School embarked on a terrarium-making project, turning glass jars into miniature ecosystems. This hands-on activity was designed to complement their geography lesson on the water cycle, providing a tangible way to observe the processes of evaporation, condensation, and the sustaining of life within a closed system.
The Process: Building a World in a Jar
Armed with glass jars, pebbles, sand, and plants, each student set out to create their own terrarium. The classroom buzzed with excitement as they layered wet and dry sand, carefully placed stones, and tenderly planted greenery. With a sprinkle of water and a sealed lid, these jars were transformed into self-contained habitats, ready to reveal the wonders of the water cycle.
Observations: A Weekend of Change
After a weekend in the classroom, the students returned to a fascinating display. Some terrariums showed mist clinging to the glass, others had droplets of dew, and a few even hosted new life in the form of earthworms. Each jar told a different story, illustrating the diverse outcomes of a seemingly uniform set of conditions.
Outcomes: Understanding Earth’s Natural Processes
The terrarium activity not only demonstrated water vaporization and condensation but also served as a metaphor for the Earth itself – a natural terrarium. Students learned about the delicate balance of ecosystems and the pivotal role of the water cycle in sustaining life.
Conclusion: Beyond the Classroom
This Grade 7 project is a prime example of experiential learning, where students don’t just read about the water cycle – they see it in action. It’s activities like these that position Vidhya Peetham i-School among the best CBSE schools in Salem, where education extends beyond textbooks into the realm of real-world experience.
