Lesson #1: What is Sound? Josh & Mason


What I Know
Want to know

of headphones.
you can hear sounds through your ears.
how loud sound has
to be for a person to go death.

how loud does it have to be to pop your ears.
In this lesson we will be exploring sound and how it is created. At the end of the lesson you will complete the table below.

Sounds we have heard:
Ways to make sounds:
trash cans smashing.

ziposs fire burning
smash trash cans together.

clicking lid on lighter.

Lesson #2: How does sound travel?

http://www.pulsethemovie.com/ (skip intro, enter, click on newsflash Go button)

You had a chance to test different materials to see how sounds travels through them using a tuning fork. You tested: wood, aluminum, foil, and twine.
Please copy and paste the questions below and answer them on your team page with your partner.

1. Which materials did you find that the sound traveled through the best (made the loudest sound)?yard stick


2. Put the materials in order from loudest to quietest?
loudest:yard stick
middle:aluimin
quietest:string


3. Why do you think the sound was different?
the leanthes

4. Wht did you observe about the waves?
Loud:
Soft:
High:
Low:


Lesson #3: What is pitch? How are pitch and volume different?

Make a prediction about the sound a large, medium & small sized nail will produce & give a reason for your prediction. Then make an audicity file to show the sound you produced.In your audicity file make sure you show the different pitches and explain how the different pitches are produced. Remember to save it as a .wav not an .aup and upload it to the table below.





Size of Nail
Sound Predicted
Reason for your prediction
Sound Produced (This is where you will put your audacity file)
Large
bing
i think it would be lower

Medium
bong
it think it would be in the middle

Small
bing
i think it would be high


1. What is pitch?lowness of highness of a sound

2. What is volume?amount of sound loud or quite

3. What is frequency?a sound waves pitch

4.What is a decibil? unit of measuring of a sound

Lesson #4: How are vibrations and pitch related or connected?

Lesson #5: Exploring Pitch



Length of Ruler Extending
over Edge of Table
What I hear:
Pitch
What I see:
Vibrations
2 inch
short low sound
little vibrations
4 inch
short medium pich sound
mediuim vibrations
6 inch
short high sound
a lot of vibrations
8 inch
short high sound
a lot of vibrations

Lessons 4+5 Questions:


1.How did the sound change when you made the ruler extend over the edge of the table and made it vibrate?It lasted longer.


2.Why do you think it did this?the leanth of the ruler made it higher or lower.


3.How do you make the pitch of a sound higher or lower?making it longer or shorter


4.Give an example to support your answer.when it was longer it was higher.

Lesson #6: What does an ear look like? How does it work?


http://www.youtube.com/watch?v=skXQ6PuIc4sHow the ear works paper model
http://faculty.washington.edu/chudler/bigear.html (model and games)
1.Creating our own eardrums


1.What is causing the model eardrum to vibrate?

2.What do you observe when the noisemaker and the model eardrum are closer together?

3.What do you observe when the noisemaker is far away from the model eardrum?

4.What are some ways to prevent your hearing from being damaged by loud sounds?

5.What do you think a hearing aid is used for?

Homework for Lesson 6: How does the ear work? Click on the link below and learn more about how the ear works. When you finish write a paragraph to explain how the eardrum works. This organizer will help you create your paragraph. http://www.tinnitus.asn.au/earworks.htm
do you want to know how the ear works then lets go through a journey

the sound goes through the ear then it goes through the ear canal.

next the ear drum.and then there are three bones.

and the cochleha little hairs in it and the noise turns into electric impulses

then it goes to the brain
​​
hoped you like the journey through the ear- =Josh=



The human ear. The human ear is the body part on the side of your head right now. You use this to hear everything. Without ears you can’t hear ANEYTHING. but wait not every one can hear as much as we can. some peaple need help hearing and one thing that can help is a hearing aid…
BUT WAIT AGAIN!some peaple are something called death these peaple can hear anything not even with the help of the hearing aid. There are 3 parts of the ear ezternal ear, middle ear, internal ear.

Lesson #7: How do we change pitch?

Create a one-stringed pegboard harp.

1. Where you able to make high or low pitched sounds?tighening or loosining.

2. How did you change the string to make different sounds?tightining it

3. How do you think sound will change if you tighten the string?I think the sound will get higher.

4. What is tension? adjusting the streanth
of the strings
*If there is extra time you may add strings to make a four stringed pegboard harp. The strings must be all different lengths.

Lesson #8- How does a human vocal cord work?
Create model of your vocal cords.

1.How are rubberbands like strings? when you pluck them they make different sound cause the different sizes.

2.How are they different? the bigger the vocal cords the lower the sounds.

3.How could sounds be produced with rubber bands? by streaching them out and plucking them.

4.How was the sound produced using your model?by plucking the rubber bands.

5.What are some ways you were able to change the pitch of the sound? by switching rubber bands.

Conclusion: Let's Make Some Harmonious Sounds

Option #1- Create a music video using the flip cameras, bring in one or two household items that are not a “traditional” instrument! Will be performed live in front of the class!http://www.youtube.com/watch?v=oh_owBp9zPU (describes how stomp does it!) You may join with another group to do this.

Option #2- Using Glogster create a sound card using at least 5 different sounds. This is an example of how it might look. http://www.smm.org/sound/soundcard/top.html Sound cards with pictures (audacity)
