Sound (Travel, Movement, Transfer)

 Once you have found your partner you must print out the Webquest worksheet  by clicking on the link at the bottom of this page. Be sure to fill out your worksheet and share your thoughts about the webquest with your partner.

To find out about sound click on the following websites. Follow the directions on the website and use the navigation tools to get around.

Matter and Molecules
Go to this website to begin:
http://www.knowitall.org/nasa/simulations/sound/molecules.html
Use this website to answer the following questions. It will help you learn about matter and molecules.
1)What is matter?
2)How is sound created?
3)Can molecules be seen by the naked eye?
Once you have answered the questions click on the link to take you back to the learning modules.

Sound Waves
Next, go to:  http://www.knowitall.org/nasa/simulations/sound/wave.html
Once you get to this page follow the directions to learn about sound waves or how sound travels.

Be sure to write the definitions found on this page on your worksheet.

*crest
*trought
*wavelength
*amplitude
*frequency

1) What does the term pitch mean?
2)What do you notice about the 3 sound waves when you click on them?

Once you're finished click on the link at the bottom of the page to take you back to the learning modules.

How Sound Travels
Click on this link to answer the questions about how sound travels.
http://www.knowitall.org/nasa/simulations/sound/howsound.html

1)What determines the speed at which sound travels from one place to another?
2)What is medium when talking about sound?
3)Sound travels the fastest through which medium?
4)Sound travels the slowest through what medium?
5)If there is no medium can sound be transmitted?

Next, play the game with Fred Frog to see how fast sound travels through each medium (Space, Land, Water). Follow the directions on the page to play the game. Be sure to write down the times on  your worksheet.

1)If sound waves travelling through the air meet a hard obstacle like concrete, how much of the sound wave is reflected?
2)Is sound transmitted through cloth better than through concrete?
