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...

Light travels as transverse waves and can travel through a vacuum. Sound travels as longitudinal waves and needs to travel through a solid, liquid or gas. Read about the properties of light and of sound, and learn the differences between...

Learners investigate the nature of a sound wave, sound properties, resonance, musical instruments, and standing waves. The tutorial consists of lessons and problems to check for understanding.

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel...

Discover the acoustical properties of brass instruments from this well researched site provided by the University of New South Wales. Everything from lip control to bell shape is discussed as it applies to frequencies and harmonics.

In this succinct lesson plan, students will compare the sounds produced by tuning forks and observe the behavior of sound waves in different media.

A video and a short quiz on how sound travels in waves, its properties, and how to measure it.

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

How can scientists lump heat, light and sound together when investigating properties and behaviors? This learning module will address that question through a series of activities.

An easy to do activity that investigates the simple observable properties of sound waves. The activity is presented in lesson plan format that meets NSES standards.

This interactive activity adapted from the University of Utah's ASPIRE Lab provides an overview of the characteristics and properties of various types of waves, including light waves, sound waves, and water waves.

Students investigate sound in their environment, particularly how sounds impact their lives. At the beginning of the unit, students use online simulations to investigate the properties of sound and learn about the components of a sound...

This resource explains how sound is characterized. It provides links to sound properties and their perception as well as properties of waves.

This is a five-question quiz related to the passage "The Effects of Ear Canal Acoustics on Hearing Ability."

An easy experiment through which students explore sound waves while tapping their fingers on a desk or table in a quiet room.

The concept of pitch and frequency is covered in this tutorial. Learn what frequency and pitch are, the difference between infra sound and ultrasonic frequencies, and how pitch is related to the frequency of a sound.

In this module, students investigate the properties and behavior of different types of waves.

Great animations showing how sound is produced.

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.

Lighting is responsible for nearly one-third of the electricity use in buildings. One of the best ways to conserve energy is to make sure the lights are turned off when no one is in a room. This process can be automated using motion...

This site from Architectural Acoustics and Lighting provides a discussion of various factors affecting the acoustics of a given room. Room dimensions, the wavelength of the sound wave, the physical characteristics of the walls, the...
