Lesson 1 Producing and Detecting Sound
Lesson 2 Properties of Sound Waves
Lesson 3 Using Sound Waves
Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby buildings. Katerina Kaouri details how scientists use math to predict sonic booms' paths in the atmosphere, where they will land, and how loud they will be.
Sound waves are all around us, and when harnessed, can do some super cool things. Trace looks at a few ways we're using the power of sound waves to our advantage.
1. Understand that sound is a form of energy that travels in waves referred to as compressional waves
2. Understand that sound waves can travel through different mediums, including solids, liquids, and gases
3. Understand and observe that sound waves travel in a given direction until an outside force or object gets in the way of its motion and reflects it
4. Observe a variety of sound waves in lab stations and record their observations on their lab sheet.

Over the course of the trial, students will learn:
How vibrating objects create sound
How sound waves travel through the air and other material
Why sound takes time to travel

In this live-action, fast-paced program, Bill Nye the Science Guy explains how each musical note and every tone of each instrument is, in fact, a unique sound wave. Along the way, students will learn about the science behind getting the exact sound waves in the pattern desired. Features comedy, music videos, interviews with real scientists and hands-on experiments to make the concepts presented understandable and fun.
23 min 8 sec.
Featuring peer hosts, colorful graphics, animated sequences and detailed diagrams, this educational, live-action program explores the principles of sound. Topics covered include how sound is created, properties of sound waves, and how sound waves travel.

In Musical Instruments, inhabitants of Mammoth Island invite a visiting inventor to a concert of mammoth proportions! Instead of playing instruments, the islanders rely on musical mammoths for entertainment. After the performance, which includes a rather dangerous stampede, the inventor shares what he knows about musical instruments with a young islander named Olive and her friends. Sound waves of different frequencies result in different pitches, and instruments of those different pitches are combined to produce music. The islanders learn the principles behind various wind, string, brass and percussion instruments and the various sounds they produce. And the result is music to their ears! Part of the multivolume series The Way Things Work, based on the best-selling book by David Macaulay.

In Sound, the inhabitants of Mammoth Island learn how sound energy travels in waves. While herding their mammoths towards fresh pasture through a maze of canyons, someone sneezes and the sound reverberates, startling the timid mammoths and causing them to run away! A visiting inventor explains that sounds are caused by the movement of molecules -- what scientists refer to as vibrations. Thinking about how our ears translate vibrations into sound leads a bright young Islander, Olive, to create a primitive microphone. The islanders use this device with an amplifier and loudspeaker to send out a loud trumpeting mammoth call, and the lost herd reunites and travels to greener pastures. Part of the multivolume series The Way Things Work, based on the best-selling book by David Macaulay.

The members of a musically challenged rock band serve as humorous hosts for a free-wheeling film about sound. Along the way, students learn how sound waves travel and how they're measured, the properties of sound, what causes echoes, and how our ears actually hear. In addition, viewers will see how humans use sound to locate military targets and study earthquakes. Simple experiments, animation, and songs help students understand why sound is cool!

A door closes. A horn beeps. A crowd roars. Sound waves travel outward in all directions from the source. They can all be heard, but how? Did they travel directly to the ears? Perhaps they bounced off another object first or traveled through a different medium, changing speed along the way. Students learn how sound waves travel and about their properties, frequency, wavelength, amplitude and pitch. With a fun hands-on activity, this program illustrates the key concepts of sound and its properties. One of 16 volumes in the Physical Science in Action Video Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Physical Science: properties & changes of properties in matter, motions & forces, and transfer of energy.

The Design Squad teams compete to create original musical instruments -- one stringed and one percussive -- for the band Off White Noise. The instruments are put to the test when Off White Noise rocks out at the Middle East nightclub. ''Design Squad'' is an award-winning reality competition series whose goal is to increase students' knowledge of engineering, the design process, and the roles of engineering and design in society.
