Musical Instruments part 2

Students experiment with various sound sources, including their voice and different musical instruments to gain an understanding of the connection between sound and vibration.

Students experiment with various sound sources, including straw instruments and water bottles, to gain an understanding of the connection between sound and vibration. This lesson is designed for uses AFTER the Sound and Music introductory lesson.

Wave Basics

Students explore the PhET Interactive Simulation “Wave on a String” focusing on amplitude and frequency as well
as wave travel.

Tuning Fork Discovery

Students study a brief history of sound, examine the role of tuning forks in this history and then conduct experiments with tuning forks.

Echolocation and SONAR: Outdoor Unit

Students explore the speed of sound by experiencing the delay for sound to reach them when they know a noise has been made.

How Dolphins Use Sound

This activity is a visual, class or group discussion version of the Echolocation and SONAR homework. The reading from that activity has been put into a visual power point with student questions placed at key points.

Sound and Music

Students explore the physics of sound, how the ear hears and how musical instruments work through interactive demonstrations and student activities.

Echolocation and SONAR: Indoor Unit

Students explore the idea of how it feels to use sound to locate objects.

Echolocation Wrap-Up

This activity brings together the hands-on activities done in indoor and outdoor echolocation units and helps students understand why and how echolocation works.

Echolocation and SONAR Quiz

Pre and Post quiz covering the learning goals from the echolocation activities.

Giant Acoustics Wordsearch

This word search uses 36 acoustics terms found in the lessons and will take a minimum of 2 hours to complete.

Sound Measures

Students use a sound level meter to measure, compare and graph sound levels in different environments.

How Loud is Too Loud?

Students create wheel that will show them various sound sources, the decibels produced by that sound, and allowable time they can be exposed to that level of sound.
