Chemistry STEM workshops
Some of our Form 5 and Form 4 Chemistry students participated in a silver restoration workshop and a gold-electroplating workshop organized by our Chemistry Department and Chow Sang Sang Precious Metal Laboratory on 17 and 24 February 2023 respectively. They applied and integrated their knowledge of metal corrosion and electroplating to tackle corrosion problems in silver jewellery and make their own gold-plated crafts.
