Sound Waves

How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

Dive into the mystery of sound waves!  Scholars brainstorm questions about how sound travels and why different items make different sounds. They then conduct experiments to answer their questions.

Light waves and sound waves are the focus of this science lesson designed for 5th graders. Besides discovering how these waves travel, learners also discover the basic properties of waves, and analyze data tables and graphs. The...

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

Make sound waves visible with an experiment that asks middle schoolers to build a model ear drum using plastic bottles, rubber bands, plastic wrap, and sand-like substances.

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Using a karaoke machine, a guitar, and other devices, learners explore the way sound waves travel. Using this hands on approach, learners can get a better understanding of wavelength, frequency, and more.

Students explore and learn about the concept of echolocation. In this echolocation lesson, students explore how animals and engineers use echolocation (seeing under water) and sound waves to look and hear things under the deep water.

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...
