The objectives of the competition are to promote the interest of our youth in science and technology, to develop their creativity through better understanding and innovative application of science and technology, and to inspire their intellectual and career interest in science and technology. This year a team of 6C students investigated the absorption properties of a naturally occuring polymer, sodium alginate, extracted from seaweed towards 18 metal ions. They found that the polarizing power and cationic size of metal ions governed the absorption efficiency. Another team of 6D and S4 students investigated the synthesis, conducting properties and the application of an artificial polymer, polyaniline. They developed a system to detect various acidic, alkaline and toxic gases based on the research of polyaniline.
