In this challenge, students will design and construct at least one instrument that will be used to play a recognizable song. Students can use recyclable materials or the 3D printer to build their instruments. The instrument must be able to play a variety of notes with definite tones and frequencies. Bonus points will be awarded to students who form a band and play a song together and/or compose their own piece of music.

This activity should be developed in groups of 3 learners. Teachers should help maintain the motivation of the learners particularly when they are struggling with their instrument concept.
