Sound

Lesson 10-11

Standard: Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Indicator: Recall that vibrating objects produce sound and that vibrations can be transferred from one material to another Generate questions such as “What if?” or “How?” about objects, organisms, and events in the environment and use those questions to conduct a simple scientific investigation Predict the outcome of a simple investigation and compare the result with the prediction.

Vocabulary vibrations sound Essential Question How are sounds produced?

Lesson Hook Prepare a chart with three columns…. Sounds We Have Heard Ways to Make Sound Questions?

Sound is made when an object vibrates. Teacher Model (I do):

What are some ways that vibrations make sounds?

Let’s make some vibrations!!

How is Sound Made? A Segment of: A First Look: SoundA First Look: Sound

A guitar string vibrates when you strum it. This makes the sound you hear!

Plucking a rubber band makes it vibrate and creates a sound!

You make a sound when the vocal cords inside your throat vibrate. If you put your hands on your throat and sing, you can feel the vibrations!

Click for video clip about vibrations Now you try to make some sounds with tuning forks!

Hitting a ruler on a desk, makes the ruler vibrate back and forth. This makes the sound you hear.

All sounds are made by vibrations ! Click for video clip

Lesson Closure: Wrap up discussion from “Making Vibrations.”

Lesson 12

Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Standard: Indicator: Recall that vibrating objects produce sound and that vibrations can be transferred from one material to another Generate questions such as “What if?” or “How?” about objects, organisms, and events in the environment and use those questions to conduct a simple scientific investigation Predict the outcome of a simple investigation and compare the result with the prediction Explain why similar investigations might produce different results Use appropriate safety procedures when conducting investigations.

Vocabulary vibrations sound Essential Question Can sound travel through solids, liquids, and gases?

How does sound travel from one place to another? Vibrations can be transferred from one material to another causing that material to vibrate. Lesson Hook:

How can we hear the sound of a plane when we are on the ground? When the planes engines vibrate, they make sounds. These vibrations (sounds) travel through the air until they reach us on the ground! Teacher Model (I do):

Let’s investigate how sound travels through air, water, string, and wood! Guided Practice/Independent Practice :

Lesson Closure: Turn and Talk: Discuss with a neighbor which material you think sound traveled through best. Share Out! Sound travels best through solids!!!!

Lesson 13

Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Standard: Indicator: Recall that vibrating objects produce sound and that vibrations can be transferred from one material to another.

Vocabulary vibrations sound Essential Question Can sound travel through solids, liquids, and gases?

Lesson Hook Can salt dance?

Here’s a cool experiment with sound waves! What did you learn from this activity? Guided Practice (We do):

How Do Sound Waves Travel Through Different Materials? A Segment of: A First Look: SoundA First Look: Sound

Sound waves can travel through solids, liquids, and gases, but they cannot travel through empty space where there are no particles of matter to vibrate. Click button

Click for video clip about how sound travels through materials Sound travels better through solids than through liquids. Sound travels better through liquid than through air. Sound travels the best through solids! Sound travels the worst through air!

Here's how you can see sound waves! Watch the sound waves travel through the flames!

Lesson Closure/Independent Practice (You do): Answer in your science notebook: 1.What happens to the salt when the rubber band is plucked? Why? 2.Does it changes how the salt dances if you change how hard you pluck the rubber band? 3.Does it make a difference what direction the tub on which you are plucking the rubber band is facing?

Lesson 14

Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Standard: Indicator: Compare the pitch and volume of different sounds Recognize the ways to change the volume of sound Explain how the vibration of an object affects pitch.

Vocabulary vibrations sound Essential Question How does distance affect volume?

Lesson Hook Why is the volume getting louder?

Not all sounds are the same Some sounds are loud Some sounds are soft This is called Volume Teacher Model (I do):

Boom Box Science Experiment Guided Practice (We do):

Lesson Closure/Indpendent Practice (You do): In your science notebook, answer the following questions. 1.How did the volume change as you walked away from the radio inside? Explain why. 2.How did the volume change as you walked away from the radio outside? Explain why. 3.Compare how the volume changed from inside to outside. Explain why it changed.

Lesson 15

Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Standard: Indicator: Recall that vibrating objects produce sound and that vibrations can be transferred from one material to another Compare the pitch and volume of different sounds.

Vocabulary vibrations Sound pitch Essential Question Does the length of an object affect its vibration (pitch)?

Lesson Hook High or Low?

Not all sounds are the same Some sounds are high Some sounds are low This is called Pitch Teacher Model (I do):

Sounds Produced by Nails and Sounds Produced by Rulers Experiments Guided Practice (We do):

Lesson Closure/Independent Practice (You do): With a partner, discuss other examples of different pitches that you might hear daily. Share Out!

Lesson 16

Standard 3-5: The student will demonstrate an understanding of how motion and sound are affected by a push or pull on an object and the vibrations of an object. Standard: Indicator: Compare the pitch and volume of different sounds Explain how the vibration of an object affects pitch.

Vocabulary vibrations Sound pitch Essential Question What affects the pitch of a sound?

Click on the picture for a video that might help! Try the Quick Lab on page 359 of the Textbook (Changing Sounds). Lesson Hook Guided Practice (We do):

Here is another version of that experiment!

Lesson Closure/Independent Practice (You do): In your science notebook, explain how the length of the straw affected the pitch that was heard.
