Introduction
Part 1. Introduction
Sound is the energy things produce when they vibrate (move back and forth quickly). If you bang a drum, you make the tight skin vibrate at very high speed (it's so fast that you can't usually see it), forcing the air all around it to vibrate as well. As the air moves, it carries energy out from the drum in all directions. Eventually, even the air inside your ears starts vibrating—and that's when you begin to perceive the vibrating drum as a sound. In short, there are two different aspects to sound: there's a physical process that produces sound energy to start with and sends it shooting through the air, and there's a separate psychological process that happens inside our ears and brains, which convert the incoming sound energy into sensations we interpret as noises, speech, and music.

Process
Part 3. Process
Using information you have obtained from the videos, articles, and simulations in this webquest create an original visual presentation of sound waves. Make sure your visual is clear and could be easily understood by students in another grade level with less experience. Be prepared to present to class. Be prepared to answer questions from classmates. See evaluation tab for full rubric.

Conclusion
Part 5. Conclusion
I hope you have gained a better insight about sound waves by completing this activity. I also hope you enjoyed finding out information about our very own West Virginia native, Charles E. Yeager and his importance on this topic.
Sounds waves can be either pulse waves or periodic waves. A pulse wave is characterized as one assault to the medium while periodic waves are characterized as a series of successive assaults on the medium. Sound waves can be described by period, wavelength, amplitude, and for periodic waves we can include frequency.
Frequency is the number of waves in a given time. The period is the time it takes for one wave to fully assault the medium. Wavelength is measured from crest to crest or trough to trough. Amplitude characterizes the wave’s energy or intensity. (Information in this conclusion was retrieved from https://www.thermaxxjackets.com/sound-waves-and-characteristics/).
