Understanding Sound Waves

Students work in teams to make decisions about what types of materials and shapes might amplify sound during a DW science class experiment. They test recorded musical sound clips on construction paper, cardboard, aluminum foil, and plastic.

It's all part of Daniel Wright’s Next Generation Science Standards where students develop and build a model to show how sound waves are reflected, absorbed, or transmitted through various materials and shapes. This helps them better understand how sound travels or interacts with other objects.

“By experimenting, designing, and building, students better understand the properties of sound waves as opposed to simply memorizing words and definitions. If exposed to sound concepts in the future, they should be able to better recall what they learned in seventh-grade through this hands-on experience,” said Science Teacher Anthony Hafner.
