Simple Instruments
Students work with partners to create four different instruments to investigate the frequency of the sounds they make. Teams may choose to make a shoebox guitar, water-glass xylophone, straw panpipe or a soda bottle organ (or all four!). Conduct this activity in conjunction with Lesson 3 of the Sound and Light unit.

Acoustic engineers help design effective auditoriums (and other spaces) so that everyone in the audience can hear the music that is being produced on stage. They also design music-related equipment such as recording equipment, music players, public address systems, microphones, speakers and headphones. To design these items, they must understand music and the frequencies at which different notes are formed.
After this activity, students should be able to explain that high frequencies produce high-pitched sounds, and low frequencies produce low-pitched sounds.
