Organized by the East Zone Science and Technology Centre at Victoria Junior College and sponsored by the A*Star Research Institute, the East Zone A*star Science Fair aims to provide students with the experience of conducting an investigative science project and sharing their findings with others.

In the Open Category for upper secondary students from all local secondary and Integrated Programme schools, the team comprising Kiefer Ong Xian Yao (3S1), Pierre Yap Yu Song (3S1) and Brandon Ong Yen Chow (3S2) clinched the only Gold award. Their project entailed magnetizing carbonized banana peel and synthesizing versatile and eco-friendly adsorbents which can be used to remove atrazine (a herbicide), lead(II) metal ions and brilliant green (a toxic dye) from water. The magnetic property of the adsorbents allows them to be reused for at least 3 cycles with no significant loss in adsorption capability.
