A lab activity on sound waves is presented on this website. Students will learn about sound waves produced by different objects in this activity. There are also a set of discussion questions and two other variations of the lab exercise.

In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and...

Kids learn by experimenting with science. A project showing how sound waves move and propagate.

Lesson about sound waves of high and low sounds. Students learn through a website, activites with rope, rulers and rubber bands on cups, and with Audacity software. Lesson is written for early elementary music students but could also be...

Sound! How does it work? All you need to know about it is found here through a series of Q&As. Educators will find useful lesson plans.

Sound the alarm! Fire alarms and fire trucks are perfect examples of communicating with light and sound. Students will begin to understand the engineering principles behind why fire alarms and fire engines use both light and sound to...

In this direct instruction lesson, learners draw sketches in their science notebooks in order to make sense of wave properties. Resources include a slideshow presentation on the properties of waves and multiple examples of student work.

Learners investigate sound. Some topics examined are Doppler effect, interference of waves, and sound waves. The resource includes example problems with solutions and a chapter quiz.

This document will give you "extra" information and opportunities to build your understanding of sound so that you can be better prepared to facilitate the sound lessons with your students.

Discusses the characteristics of sound waves and the conditions that affect the speed of sound.

In this very detailed lesson plan, students explore and create a stringed instrument that demonstrates their understanding of sound waves and how energy is transferred. Multiple videos are included showing this lesson in action in a...

[Free Registration/Login may be required to access all resource tools.] This guide gives a detailed overview of mechanical waves and the characteristics of waves. Covers wave behavior, including types of interference, resonance, and the...

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

This list describes common misconceptions children have about sound and the scientific explanation for those ideas.

In this activity, students use a variety of materials to design and create headphones that absorb sound.

Kids learn more about the science and physics of sound. Pitch, acoustics, and the doppler effect. How the frequency of the sound wave affects the pitch we hear.

Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe...

In this lesson plan, students learn about sound. Girls and boys are introduced to the concept of frequency and how it applies to musical sounds.

In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon...

Great activity for primary and intermediate students to learn why objects make noise. This can be organized in stations or in groups of students.

To further their understanding of sound energy, students identify the different pitches and frequencies created by a vibrating ruler and a straw kazoo. They create high- and low-pitch sound waves.

Explore bats' navigation systems by experimenting with echolocation. Approximate an object's distance by analyzing reflected sound waves, measuring the delay in sound and calculating the ratio to the speed of sound.

[Free Registration/Login may be required to access all resource tools.] Students investigate behaviors of waves, and explore the Doppler effect phenomenon.
