Sound is someone talking but not always.
Sound can be loud or soft.
the sound is sometimes slow.
How the sound works?
Why did the inventor want to invent sound?

Lesson #1: What is Sound? Caroline & Nataly

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:
clapping and stomping,druming,tapping,clicking and
With hands,feets,drums,paper,
opening and closing lighters,trashcan,bars,

Lesson #2: How does sound travel? (how does sound work and travel) (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)?

2. Put the materials in order from loudest to quietest?

3. Why do you think the sound was different?
Sometimes it was loud sometimes it was quit.

4. Wht did you observe about the waves?

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)
drum is vert

someone talking
a peson is loud

because it is not realy talking.

1. What is pitch?

2. What is volume?
It's kind of loud and it is someone or an instrument talking

3. What is frequency?

4.What is a decibel?

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

What I see
Length of ruler extending
over edge
Predictions and
Predictions and
Actual length:
low because most of the ruler is hanging.
low sounds
I predict that it will make a large sound.
big vibrations
Actual Length:
medium because half of the ruler is hanging
higher than first soound
I predict that it will medium vibration
faster than first one
Actual Length:
high sound because not a lot of the ruler is hanging off
I predict that the vibrations will be slow
faster but not as big because not as much ruler to vibrate

Lesson #5: Exploring Pitch

Length of Ruler Extending
over Edge of Table
What I hear:
What I see:

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?

2.Why do you think it did this?

3.How do you make the pitch of a sound higher or lower?

4.Give an example to support your answer.

Lesson #6: What does an ear look like? How does it work? the ear works paper model (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.
Topic Sentence
Hello there!Today we are going to learn about ears.
Lets get started!!!!!!!!!!!!!!!
Detail 1
First there is two ears on your head.The ears is something on your head so you can listen well !!!
Detail 2
All the noise that someone's talking it travels through your ear and in your head so you c an listen.
Detail 3
If it is cold the sound travels slower when it is hot it travels faster!
Detail 4 (optional)
The ear consist of three parts:outer ear ,middle ear and the inner ear .
Well !!! This was fun if you ever want to know
more about this than check out are Science page by Caroline M and Nataly A !!!!!!!!!!!!!!!

Lesson #7: How do we change pitch?

Create a one-stringed pegboard harp.

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

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

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

4. What is tension?

*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?
They are large and flecsible.

2.How are they different?
They are hard . But strings are not hard.

3.How could sounds be produced with rubber bands?
Vocal cords open for breathing.

4.How was the sound produced using your model?
Like a guitard and like a little drum.I's coooooooooooool !!!!!!!!!!!!!

5.What are some ways you were able to change the pitch of the sound?
Make it fast or slow or soft.

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! (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. Sound cards with pictures (audacity)
