Students complete a probe to uncover their ideas about how sound interacts with matter.
Students consider why many people dislike the sound of their own voice when recorded, but like their singing voice better in the shower.
Students conduct labs to explore how sound interacts with various media.
Students read articles and view a video to explain how waves interact with media, then make a model to explain these phenomena.
Students visit several stations to explain how waves interact to produce constructive and destructive wave interference patterns. Students make an initial model, give and receive feedback with peers, and then revise models.
Students take a quiz and develop a sound wave model.
Students watch a video clip, explore tuning forks, and develop a model to explain how sound travels faster in liquid than in air.
In the previous cycle, students learned how the properties of a sound wave affect the type of sound produced.
In this cycle, students discover how sound interacts with different types of matter to answer the guiding question, “How does sound interact with various types of matter?” They will conduct an experiment and discover that the type of matter a sound wave interacts with can change the volume and/or pitch of the sound. Students obtain and evaluate information to determine how the properties of matter affect how waves interact with matter. They then apply this knowledge to wave interference and model the properties of waves after an interference with another wave.
Students will revisit how waves interact with matter in the next concept when they discuss wave and matter interactions through the lens of light waves.
