In this classroom guided inquiry instructional activity, young scholars will rotate through five stations of various sound instruments to look at how length affects pitch. The five sound stations include: straw flutes, xylophone, water phone, palm pipes, and kalimba. They will observe what happens when the length of the vibrating sound source changes. Students will record their observations in their science notebooks throughout the instructional activity. Before beginning the stations, young scholars will develop a hypothesis as to what they think they will discover about length and pitch from these explorations. Students will draw a conclusion on length and pitch based on their investigation.
