Lesson #1: What is Sound? Tess & Marin


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:
What we know:
Sound controls everything you hear.
If we didn't have sound then everything would be silent and it would be like you didn't have ears and you didn't have a mouth.
Their are many sounds.
Questions you have:
How does sound work?
What makes sound work?
How did sound get its name?
How do you control all of the sound/noises that things make or do you not?

Lesson #2: How does sound travel?

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)? The meterstick

2. Put the materials in order from loudest to quietest? meterstick, string, and the tin foil.

3. Why do you think the sound was different? because of the amount of thickness was different and the length was different.

4. Wht did you observe about the waves?
Loud: When th sound is loud it always strats loud and increases the loudness of the sound.
Soft: Soft is when you start out really low and then the sound waves disappear.
High: High is when the sound is high pitched and then it slows down and the sound gets low.
Low: Low is when the sound seems very deep.


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.
Pitch is

Size of Nail
Sound Predicted
Reason for your prediction
Sound Produced (This is where you will put your audacity file)
Large
high.
because the sound waves
are larger.

Medium
high/low
because the sound waves
are not to high and not to low.

Small
low
because the sound waves
are small.


1. What is pitch? a pitch can be low high or medium.

2. What is volume? is a sound with different levels.

3. What is frequency?it is a eledtric wave.

4.What is a decibel? is a loud noise.

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

calm 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 made a clack when it went over the desk and when it vibrated it went like "bzzzz."

2.Why do you think it did this? because when something vibrates it goes like "bzzzzz."

3.How do you make the pitch of a sound higher or lower? you tap it harder to make it louder and tap it gently to make it quietly.
4.Give an example to support your answer. so you have to tap it light to make it low and have to tap it hard to make it loud .
Lesson #6: What does an ear look like? How does it work?

1.Creating our own eardrums


1.What is causing the model eardrum to vibrate? The noisemaker causes the eardrum model to vibrate.

2.What do you observe when the noisemaker and the model eardrum are closer together? The salt moves all over the place.

3.What do you observe when the noisemaker is far away from the model eardrum? The salt doesn't move around as much.

4.What are some ways to prevent your hearing from being damaged by loud sounds? A couple ways are to not put anything in your ear or to listen to anything very loud like blasting music.

5.What do you think a hearing aid is used for? I think a hearing aid is used for people who have a hard time hearing.

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
Topic Sentence
sounds are every were!
Detail 1
sound are things you hear . there are so many sounds
and there all different.
Detail 2
your ears help you hear sounds. there's a thing inside
your ear called the ear canal it helps the sound go into your
brain.
Detail 3
If your ear gets clogged or you put something in your ear
wax will help you unclog it but if you put something it your ear
you could lose your hearing.
Detail 4 (optional)

Conclusion
I think its a good idea if we don't put something in are ears.

Paragraph written: HOW THE EAR WORKS
Sounds are every where!
Sounds are things you hear.There are so many sounds ans they're all different.
Your ears help you hear.There's a thing inside your ear called the ear canal.It helps the sound go into your brain.
If your ears get clogged or you pust something in your ear,ear wax will help you unclog it.If you put something in
your ear you could lose your hearing.
I think it's a good idea if we don't put anything in our ears!

Lesson #7: How do we change pitch?

Create a one-stringed pegboard harp.

1. Where you able to make high or low pitched sounds? when its upsidedown they both are louder but especaily the 2nd string.

2. How did you change the string to make different sounds?We just turned it upsidedown and and twisted the string.

3. How do you think sound will change if you tighten the string?it will vibrate and we less loose.

4. What is tension? A string thats tight or loose

*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? Rubberbands are like string because sometimes they make alike or the same sounds.

2.How are they different? They are different because they feel different ways and sometimes make different noises and some string is not stretchy like rubberbands are.

3.How could sounds be produced with rubber bands? There are many different ways, One example is to connect it to a nail connected to a doornob and stetch the rubberband out and then let go.

4.How was the sound produced using your model? The sound was produced by the vibrations from sound waves.

5.What are some ways you were able to change the pitch of the sound? Let's just say you were stomping your feet on the ground you could stomp it on the ground harder and change the pitch of it.

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) none SavePreviewText Editor || external image c.gif || |
