Cycle Summary
Students complete a probe to identify objects that make sound by vibrating matter.
Students use a tone simulator to generate questions around what causes differences in pitch and volume. Students use a toy xylophone to relate the object properties to the sounds they produce.
Students use an oscilloscope, tuning forks and rulers to explore the relationship between object properties and the sounds they produce.
Students use a computer simulation and a decibel meter to explore relationships between frequency, wavelength, pitch, and amplitude.

Students use a computer simulation and a decibel meter to explore relationships between frequency, wavelength, pitch, and amplitude.
Students revise model of sound waves and read about sound wave properties.
Students read, study diagrams, and watch a video about how human hearing works.
Students use a model to describe how humans hear sound.
Students take a quiz and write a CER to explain sound phenomena.
Students watch a video and make a model to explain the role of resonance in using sound to shatter glass.
In the previous concept, students learned how to model a wave and the mathematical components of a wave that give a wave its properties.
In this cycle, students will apply these properties of waves to a sound wave to answer the guiding question “What is sound, how can we model sound?” Students will produce and measure a variety of sounds to determine what properties of a wave affect the pitch and loudness of a sound. Students will then create a model of an eardrum to observe how eardrums work when sound collides with them.
They will use the properties of sound waves discussed in this cycle when they observe how sound waves interact differently with different types of matter in the next cycle.
