“It was amazing to see how a few simple layers of sand and gravel could transform murky water into something that looked clean enough to drink!”
That sense of wonder perfectly captured the spirit of discovery at Templer Park International School Rawang (TPIS), where Grade 11 students recently conducted a hands-on experiment in environmental science and chemistry. The activity focused on understanding water filtration — a vital process that highlights the importance of clean water technology in our world today.
Using everyday materials such as sand, gravel, and reused plastic bottles, students designed simple water filters to observe how physical and chemical filtration can help remove impurities from dirty water. Through this experiment, they not only deepened their understanding of scientific principles, but also explored how innovation and sustainability can work hand-in-hand to create practical solutions for real-world challenges.
Beyond the classroom, this learning experience fostered environmental awareness and creative problem-solving, encouraging students to think about how small actions — like reusing materials — can make a meaningful difference in protecting the planet.
The water produced from their experiment may not have been safe to drink just yet, but that wasn’t the point. What mattered most was the journey — one that began with curiosity, creativity, and a thirst for knowledge.
At TPIS, learning is more than theory — it’s an invitation to explore, experiment, and envision a sustainable future.
