Introduction
This WebQuest will help students learn about the properties of sound, how it differs in instruments and how to identify properties of sound waves. Students will navigate through videos and lessons to apply knowledge and answer questions along the way.
Introduction:
What creates sound? Why do instruments have so many different sounds? We hear sounds in multiple ways throughout our everyday lives. It is important to learn how sounds are made to understand the affect it has on the world around us.
Task
Task:
Today you are on a quest to investigate and learn all about sound.
STEP 1: What is sound? You will learn about the properties of sound and how it is formed.
STEP 2: Why do different instruments make different sounds?
STEP 3: How can I identify properties of sound waves?
You have a lot to learn! Keep an eye out for secret letters to unscramble and find out the mystery word!
Learning Advice:
All information will be recorded in your Science Journal. You have 15 questions to answer from watching the given videos. Additionally, at the end of the quest, you will have to compare sound waves using a word bank and the handout.
Process
Process:

Watch this video
Now, complete the activity as shown in the video.
1. How does the sound from the large can differ from the sound in the small can? Record findings in your science journal.
Answer the following questions from the video. Record the question and your answers in your science journal.
2. All sounds are made through ______________.
3. The air around us are made up of tiny ______________ that carry sound.
4. The path of vibration is called a _______.
Secret Letter: N
Watch this video
Answer the following questions from the video. Record the question and your answers in your science journal.
5. A large amount of waves in a given period of time is _________ frequency? (high or low)
6. A small amount of waves in a given period of time is _________ frequency? (high or low)
7. Higher frequencies will give us a ________ pitch. (high or low)
8. Lower frequencies will give us a ________ pitch. (high or low)
9. The loudness of sound is measured in ___________.
*One more thing!*
Volume is determined by the amplitude of the wave. Amplitude is the height of a wave, measured from the equilibrium or resting place.
Secret Letter: U
STEP 2: Why do different instruments make different sounds?
Watch this video
Answer the following questions from the video. Record the question and your answers in your science journal.
10. Why does the mandolin have a higher pitch than the guitar and banjo?
11. The higher the pitch the ________ the wavelength. (shorter or longer)
12. Why does the guitar have a different sound or tone than the mandolin?
13. Why does the banjo have a different tone than the guitar or mandolin? What materials are used?
Secret Letter: S
STEP 3: How can I identify properties of sound waves?
Watch this video on labeling a wave *ONLY* watch to 2:45.
14. Draw and label a wave in your science journal using the following terms: crest, trough, amplitude, wavelength
15. What is the horizontal line in a sound wave called?
Secret Letter: O
Go to the front table and get this handout. Cut out each sound wave and paste each one on it's own page in your journal. Underneath each wave, use the vocabulary word bank below and match the correct vocabulary to the corresponding wavelength. *Each wave should have 5 vocabulary words listed.
- high frequency
- low frequency
- long wavelength
- short wavelength
- high pitch
- low pitch
- high volume
- low volume
- high amplitude
- low amplitude
Secret Letter: D

Conclusion
Conclusion:
If you listen, there are multiple sounds existing in your everyday life and any given moment. Pay attention to them and see if you can identify any of the properties of sound you have learned about today!
You now have a greater understanding about what sound is and how it is produced. You can also explain the difference between pitch, frequency, amplitude and volume as well as how they relate to each other! Great job 4th grade science friends!
