I remember last year during assembly, our teachers put up performances about Total Defence to entertain and enlighten us. The school also invited SCDF officers to teach us how to do some preventive measures like how to put out a fire. Every year, the total defence siren will be blasted in all the school as well as the broadcasting media, this is for important day and understand the importance of protecting Singapore and be independence.
