Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

Acoustics (from Greek ακουστικός pronounced akoustikos meaning "of or for hearing, ready to hear") is the science that studies sound, in particular its production, transmission, and effects. The science of acoustics has many applications which are dependent upon the nature of the sound that is to be produced, transmitted or controlled.

Learn about art and the five senses. A lot of art is made to be seen — but what if you could touch, hear, and even smell works of art? In this episode, host Lauren Paullin shows you how to mix paints that smell like pastries and transform sounds into sketches. You'll also learn about a fascinating condition called synesthesia, which links multiple senses together in the brain so that some people can taste music, hear color, and smell words! Developed for students in grades 4- adults.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

When you spin it around, this toy sounds like a swarm of buzzing bees.

After the completion of this module students will understand that sound travels in compression waves and must have a medium to travel. Sound also travels in liquids and gases. Students will also understand that sound waves are created by vibrations and capable of transmitting energy.This module was developed by Sarah Donnelly as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.

Students gain a deeper understanding of how sound sensors work through a hands-on design challenge involving LEGO MINDSTORMS(TM) NXT taskbots and sound sensors. Student groups each program a robot computer to use to the sound of hand claps to control the robot's movement. They learn programming skills and logic design in parallel. They experience how robots can take sensor input and use it to make decisions to move and turn, similar to the human sense of hearing. A PowerPoint® presentation and pre/post quizzes are provided.

This six-day lesson provides students with an introduction to the importance of energy in their lives and the need to consider how and why we consume the energy we do. The lesson includes activities to engage students in general energy issues, including playing an award-winning Energy Choices board game, and an optional graphing activity that provides experience with MS Excel graphing and perspectives on how we use energy and how much energy we use.

This activity is an inquiry lesson where students investigate objects and their associated sound due to vibration. Students will write their observation and interpret how and why sound vibrations occurs.

In this introductory physics lab activity, students explore the sounds made by the free-end of a ruler vibrating off the end of a desk.

Students model and design the sound environment for a room. They analyze the sound performance of different materials that represent wallpaper, thick curtains, and sound-absorbing panels. Then, referring to the results of their analysis, they design another room based on certain specifications, and test their designs.

This article provides links to lessons and units about birds, bird characteristics, and penguins. Ideas for literacy integration are included, and all lessons are aligned to national standards.

Students learn about how sound sensors work, reinforcing their similarities to the human sense of hearing. They look at the hearing process sound waves converted to electrical signals sent to the brain through human ear anatomy as well as sound sensors. A mini-activity, which uses LEGO MINDSTORMS(TM) NXT intelligent bricks and sound sensors gives students a chance to experiment with the sound sensors in preparation for the associated activity involving the sound sensors and taskbots. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, the unit of decibels, and details about the LEGO sound sensor, including how readings are displayed and its three modes of programming sound input. Students take pre/post quizzes and watch a short online video. This lesson and its associated activity enable students to appreciate how robots can take sensor input and use it to make decisions to via programming.

In this classroom guided inquiry lesson, students will rotate through five stations of various sound instruments to look at how length affects pitch. Student will develop a hypothesis, make observations, and draw a conclusion about what happens when the length of the vibrating sound source changes.

Open tube resonators of nearly identical length produce sound waves with frequencies very close together. The difference between the two frequenciesy is the beat note frequency heard when two resonators (musical intruments)are slightly out-of-tune.

This activity is a classroom experiment where students learn about sound. Students will use musical instruments to explore the relationship between length and pitch.

This activity is a classroom activity where students use the inquiry method to answer the question "How is sound made?" by observing different sound producers and coming up with their own conclusion.

Students work in stations to discover what causes sound.  They extend their learning as they plan and conduct investigations demonstrating vibrating materials can transmit energy.

This activity is an experiment on how sound is energy and travels in waves. Students will investigate sound using different objects in the room.

Students will investigate how sounds are made and changed, record their findings in their journal, share these findings with the class, and develop further questions about sound.
