Sound

Arbor Scientific is providing physics and physical science teachers with a collection of student lab activities for the study of Sound. Here you can browse lab activities by title and get teachers notes, student worksheets and a list of equipment and supplies needed for each activity.

  • Wind Instruments Inquiry

    Posted on January 1, 2011 by Dr. Russell Harkay

    Students will use three simple toy instruments to explore fundamentals of sound and frequency in this inquiry exercise. Boomwhackers: Students will share a number of colored plastic tubes of various lengths.

  • Doppler Effect

    Posted on January 1, 2011 by Arbor Scientific

    The Doppler Effect occurs when an observer hears a sound from a moving source. If the sound source is moving toward the observer, the perceived frequency will be higher than the actual sound frequency. If the source is moving away from the observer, the perceived frequency will be lower.

  • Resonance: Speed of Sound

    Posted on January 1, 2011 by Arbor Scientific

    Resonance occurs when an object is made to vibrate at its natural frequency, and the vibrations reinforce themselves, becoming larger. In the case of sound, the object can be a column (or other vessel) of air, and the larger vibrations are observed as a louder sound. In this lab, students will use a tuning fork to find the resonance point of a column of air. Then they will use a simple formula to find the speed of sound.

  • Speed of Sound in Air

    Posted on January 1, 2011 by Arbor Scientific

    In this lab students will measure the amount of time for a series of echoes, and calculate the time for one echo. They will then experimentally determine the speed of sound in air. An extension activity asks students to compare the speed of sound in air to that in concrete or another solid material.
