This interactive activity adapted from the University of Utah's ASPIRE Lab shows how a pendulum's amplitude changes as you set it swinging from different distances from its axis, and how the amplitude of a sound wave changes as you adjust the volume.

The amplitude of the sound waves are the dynamics of music.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

This video segment, adapted from NOVA scienceNOW, presents basic concepts of physics behind booming sand dunes. See how surface tension affects potential and kinetic energy and how it all works together to create sound.

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

In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

Design a listening device that will allow them to listen to the sound generated by a specific object inside of a box.

Students are introduced to the concept of the image of music. They draw the image of a song after listening to it by deciding where different musical instruments were placed during recording. Finally, students further investigate audio engineering by modeling the position of microphones over a drum set to create a desired musical image.

8.01 is a first-semester freshman physics class in Newtonian Mechanics, Fluid Mechanics, and Kinetic Gas Theory. In addition to the basic concepts of Newtonian Mechanics, Fluid Mechanics, and Kinetic Gas Theory, a variety of interesting topics are covered in this course: Binary Stars, Neutron Stars, Black Holes, Resonance Phenomena, Musical Instruments, Stellar Collapse, Supernovae, Astronomical observations from very high flying balloons (lecture 35), and you will be allowed a peek into the intriguing Quantum World.

In this lesson, students learn about echolocation: what it is and how engineers use it to "see" things in the dark, or deep underwater. Also, they learn how animals use echolocation to catch their dinner and travel the ocean waters and skies without running into things.

NBC's Lester Holt looks at Newton's Third Law of Motion and the role that conservation of momentum plays whenever players collide on the football field. "Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League.

This interactive simulation, adapted from the University of Colorado's Physics Education Technology project, illustrates sound waves. Adjust the frequency and amplitude to see and hear how the waves change.

Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.

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 using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.

For middle school and up, a short course that explains acoustics (the physics of sound waves) as it relates to music and musical instruments. Suggestions for presenting some of the concepts to younger students are included.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in Lessons 6-10, they explore the concepts of light. The first lesson introduces the concepts of longitudinal and transverse waves. Students then move on to the concepts of wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, girls and boys learn all about echolocation what it is and how engineers use it to "see" things in the dark, or deep underwater. The last of the five sound lessons introduces acoustics, in which students learn how different materials reflect and absorb sound.

For grades 3-6, activities that introduce the physics of sound and music and explore the way musical instruments make sounds.

For middle school and up, an introduction to some acoustics terms and how they relate to music.
