Because most students learn best when they can put their hands around what they are learning, the activities are very "hands-on." In one activity students are asked to create a musical octave using bottles. All the activities ask students to use technology or musical instruments. The activities deal with concepts of sine waves including phase shift, amplitude, period, and addition of ordinates. In addition, sound concepts such as frequency, wavelength, and Helmhotlz resonators will also be addressed. In any given activity, both sound and math objectives will be addressed. Thus, "Sounding Off About Trig" asks students to integrate their knowledge of mathematical skills with their understanding of sound.
