AbstractSingapore does not have a compulsory education system but most children are attending school at the age of six. Scientific subjects are limited by curriculum time and the demands of written examinations, so out-of-school science activities have become very imporfllnt in teaching practical science. Freedom from the bounds of school, the specialised knowledge of professional scientists and seeing science in action has proved interesting and entertaining. Science fairs are organized in which school children exhibit projects; quizzes help them to use knowledge in problem solving. These activities are mainly supported by the Singapore National Academy of Science and the Ministry of Education.
