From Chinese calligraphy and French games to Spanish dancing, Dutch traditions, German quizzes, and cultural showcases, the day was filled with learning, creativity, and connection.

A big thank you to all the families who contributed delicious dishes for our international pot-luck lunch. Together, we celebrated the diversity that makes our community so special.

On Thursday, Grade 9 students studying World War II and Grade 11 students who have been studying authoritarian leaders students embarked on a History and German trip to Cologne, Germany.

This week Grade 9 students tested mystery solutions to uncover the building blocks of life. From starch to sugars, lipids to proteins, they used chemical indicators to reveal what’s really inside. 🔍
Iodine → starch turned blue-black
Benedict’s (+ heat) → sugars changed color (green → red)
Biuret → proteins turned violet
Emulsion test → lipids formed a cloudy white solution

This week our Grade 10 Environmental Management students participated in a trip to the Naturalis Biodiversity Center in Leiden - a fitting and enjoyable conclusion to their studies right before their study leave. Throughout the visit, students engaged with exhibits that directly supported their understanding of biodiversity and ecosystems.
