What happens when tiny living organisms get to work on sugar? Our Grade 7 Science students at Templer Park International School Rawang (TPIS) were ready to find out! 🔬✨

After learning about respiration in their Science lessons, our students took their understanding beyond the textbook and into the laboratory with a fun and simple yeast respiration experiment.

Armed with just a few everyday materials — yeast, sucrose, warm water, a conical flask and a balloon — students set up their investigation and watched closely as the experiment came to life.

🎈 Watch the Balloon Grow!

The exciting part came when the balloon slowly began to inflate! Students observed that as the yeast broke down the sugar during respiration, carbon dioxide gas was produced. The gas collected inside the flask and eventually inflated the balloon, giving students a clear and visible way to observe one of the products of respiration.

What might seem like a simple balloon experiment became a fantastic opportunity for students to connect scientific theory with real-world observation. Instead of simply memorising that respiration produces carbon dioxide, they could actually see the evidence for themselves! 👀💨

🔬 Science in Action

Throughout the activity, students practised important scientific skills such as making observations, following procedures, discussing results and drawing conclusions. They also had the opportunity to think like young scientists by asking questions about what was happening inside the flask and why the balloon was inflating.

This hands-on experience helped bring the topic of respiration to life and showed students that science isn’t just something we read about in a textbook — it’s happening all around us!

At Templer Park International School Rawang (TPIS), we believe that meaningful learning happens when students are encouraged to explore, investigate, question and discover. Through practical activities like this, our students develop not only scientific knowledge but also curiosity, confidence and a genuine excitement for learning.

From a little yeast and sugar to one very excited balloon, our Grade 7 students discovered that sometimes the best way to understand science is to see it happen right before your eyes! 🎈🧪💡

Learning by doing. Discovering by exploring. Growing through curiosity. That’s Science at TPIS! 🌱🔬
