Grade 2: Sound

Lessons at a Glance


Lesson 1: Searching for Sound

Big Idea: Sounds are produced by sources all around us. You can describe sounds in a variety of ways.

Children focus on listening carefully and making detailed descriptions of sounds as they become "sound detectives" who search for, identify, and describe sounds in their surroundings.

 

Lesson 2: What Makes Sound?

Big Idea: All sounds are made by vibrations.

Children explore ideas about how sound is produced. They learn what a vibration is, and that all sounds are produced by vibrations. They vibrate different materials to make a variety of sounds.

 

Lesson 3: Sound Travels Through Many Things

Big Idea: Sound travels through air and other materials. Sound travels through some materials better than others.

Children establish that sound travels through air. They experiment with sound traveling through different materials, and discover that some substances conduct sound better than others.

 

Lesson 4: How Sound Travels

Big Idea: Sound travels by causing vibrations in the air or in other materials.

Children demonstrate how the vibration of a sound source can cause vibrations of other materials. This activity is the basis for a basic explanation and discussion of how sound travels.

 

Lesson 5: Sound Through a String

Big Idea: Sound travels by causing vibrations in the air or in other materials.

Children send secret messages over cup-and-string telephones to explore sound vibrations and sound transmission. While experimenting, they find several ways to affect sound transmission.

 

Lesson 6: Ears Hear

Big Idea: Sound travels by causing vibrations in the air or in other materials. The shape and parts of the ear allow sound to travel through it so we can hear.

Children enact how sound travels through the three main parts of the ear.

 

Lesson 7: Exploring Pitch

Big Idea: All sounds are made by vibrations. Changing the vibrations changes the sounds.

Children describe sounds that have different pitches, identify which parts of sound-producing materials vibrate to make a sound, and reflect on the relationship between vibration and pitch.

 

Lesson 8: Exploring Volume

Big Idea: All sounds are made by vibrations. Changing the vibrations changes the sounds.

Children experiment with different materials to change the volume of sounds, and amplify sounds with a "sound box" and "sound tube." They identify materials that vibrate to make a sound, and consider the relationship between vibration and volume.

 

Lesson 9: Designing Musical Instruments

Big Idea: You can apply what you know about sound and vibration to design and build musical instruments that can change pitch and volume.

Children apply their knowledge of sound and vibration by using a variety of common materials to design percussion, wind, or stringed instruments that can change pitch and volume.

 

Lesson 10: Building Musical Instruments

Big Idea: You can apply what you know about sound and vibration to design and build musical instruments that can change pitch and volume.

Children experiment with various materials to build their musical instruments. They redesign their instruments, if necessary, and discuss problems they have implementing their designs.

 

Lesson 11: Refining Musical Instruments

Big Idea: You can apply what you know about sound and vibration to design and build musical instruments that can change pitch and volume.

Children evaluate, refine and, if necessary, redesign their musical instruments.

 

Lesson 12: Sharing Instruments

Big Idea: You can apply what you know about sound and vibration to design and build musical instruments that can change pitch and volume.

Children demonstrate their musical instruments, explain what features vibrate to produce sound, and show how to change the pitch and volume. They reflect on the design and building process.

 

Skill Building Activity 1: Observing and Describing

Big Idea: Observation is a powerful tool for learning about something, and detailed and accurate descriptions help you communicate your observations.

Children practice making accurate and detailed descriptions before and after observing a familiar object.
