This supplementary material helps learners to understand how a vibrating object can produce loud or soft sounds provided that they already have known the fact that sounds are produced when things vibrate. Simple and easy-to-do activities highlight the learning process and it is hoped that at the end of the activities, children can cite ways on how to conserve sound energy.
