Exemplars (from the NaCCA curriculum)

Collaborative learning: Learners using some local musical instruments such as drums, percussions, flutes, horns and stringed instruments describe how sound is produced. Learners then discuss the longitudinal nature of sound.
Instruments should be cut across the various ethnic groups. Opportunity for all to participate - be mindful of gender-biased groupings and should encourage peer teaching where applicable. Learners with some form of physical challenges should be assisted in the performance of the experiments.
Foster collaborations that broaden students' exposure to diverse physics-related career paths and role models.
