Water Whistle

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...

A phenomenal lesson on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

Intrigue your learners with this film. They can create a water whistle using a straw and a glass of water. This could be used as an introduction to a unit on sound waves and vibrations.

Set up a set of colorful liquid-filled bottles that produce sounds when tapped with a spoon. When teaching primary physicists about sound, they can experiment with pitch, comparing it the amount of liquid in the bottle. Which makes a...

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....

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...

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.

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.

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

Make music. Class members construct a simple record player using a paper cone and a pin. The resource provides a description of what is happening and why listeners can hear the sounds through the cone.
