13th Singapore National Crystal Growing Challenge
The finale of the 13th Singapore National Crystal Growing Challenge was held at the Chemistry Department on 26 May. This is a biennial event for secondary school, junior college and polytechnic students.
During the crystal growing process, students learn about the chemical processes behind crystallisation, factors affecting crystallisation and crystal growing techniques.
A total of 109 teams from 47 schools participated this year. The students presented ammonium cobalt (II) sulphate hexahydrate crystals for the Junior category and sodium zinc sulphate tetrahydrate crystals for the Senior category. In the Open category, they were challenged to grow a “Crystal Tree”.
After months of hard work, the students showcased their crystals at the Chemistry Teaching Laboratories for judging.
During the educational session, the participants attended a special lecture on gemology by Mr TAY Kunming, Gemologist, Director of Far East Gems and Jewellery and Far East Gemological Institute.
Prof GOH Say Song, Vice Dean (Outreach and Admissions) at the Faculty, also gave an overview of programmes offered by NUS Science.
The event culminated in the presentation of tokens of appreciation to Mr Tay and the panel of judges, as well as the presentation of awards to the winners.
