4 Groovy Activities to Teach about Vibration and Sound Energy

Most STEMists learn to appreciate vibrations as an infant when they hear their first lullaby.  And, many learn to love singing children’s songs with the accompaniment of maracas, drums and triangles in preschool and elementary school. But, do STEMists completely understand the energy of sound vibration— how we are able to hear and feel sound?
4 Groovy Activities to Teach about Vibration and Sound Energy
Sound is more than noise; it is energy.  A groovy way to teach your STEMists about sound is by listening and seeing sound waves through simple activities that demonstrate the three characteristics of sound: pitch, volume and frequency.

Here are four activities you can do with your STEMists to learn about the energy of sound vibration, and how it can be seen and heard.

Humming a Tune

Have your STEMists place their fingers on their throat and hum their favorite song. Or, ask your STEMists to hum a tune through a kazoo. Ask them to discuss what they feel. Then explain they are feeling the vibrations of their vocal chords, which vibrate to make sound. The vibrations you feel when you hum are how we make and hear sound.

Fun with a Tuning Fork

Fun with a Tuning Fork

You will need a tuning fork (available from any musical instrument store) and ping pong ball. Strike a tuning fork and place one of its tines against ping pong ball. Discuss sound waves and what happened to the ping pong ball. Why did it move? Talk with your STEMists about the changes in vibration in relation to the changes in sound.

Sounding Off with a Spatula

All you need for this activity is a metal spatula.  Lay the spatula on a table or student’s desk with its handle extended over the side.  Ask your STEMists to pull the handle down. Then, discuss what happens when they let it go.  Do they see or hear anything?  Talk about the characteristics of sound, and the similarity between the vibrations of the spatula and the vibrations of your vocal chords when you talk.

Boom Box

This activity requires a boom box, paper plate, small pieces of paper and balloons.  Blow up a balloon and hold it in front of a boom box speaker.  Then, turn up the volume and observe.  Next, place a paper plate that holds small pieces of paper on top and place it on top of the boom box.  Discuss sound energy and what happens when you turn up the volume.

Note: Remind students that loud noises can damage their ears, especially when playing loud music – whether it’s through a boom box or earphones from your iPhone!

Below are some definitions for STEMists to learn as they go through the above sound energy activities:

  • Vibration – The back and forth movement of an object; Sound is made by vibrations that are usually too fast to see.
  • Sound Energy – Audible energy that is released when playing music, talking or a clap of thunder. As explained by Exploresound.org, “Sound is produced when an object vibrates. Near the vibrating surface, air follows that surface and the air molecules begin to vibrate, or oscillate. These oscillations spread from one molecule to the next, and a sound wave moves outward from the vibrating surface.”
  • Sound Wave – A longitudinal pressure wave of audible or inaudible sound.
  • Wave – A disturbance that travels through a medium, such as air or water.

Three Properties of Sound:

  1. Volume – how loud a sound is, a measure of amplitude
  2. Pitch – how high or low a sound is in relation to wavelength and frequency
  3. Frequency– how fast a sound wave is moving (high frequency = short wavelength = high pitch)

8 Groovy Music Apps

“Music is a higher revelation than all wisdom and philosophy.  Music is the electrical soil in which the spirit lives, thinks and invents.” 
― Ludwig van Beethoven

8 Groovy Music Apps

An integration of music in the classroom can create a multisensory learning environment that is proven to improve retention and memory, increase concentration and enhance focus.

“Music stabilizes mental, physical and emotional rhythms to attain a state of deep concentration and focus in which large amounts of content information can be processed and learned. Baroque music, such as that composed by Bach, Handel or Telemann, that is 50 to 80 beats per minute creates an atmosphere of focus that leads students into deep concentration in the alpha brain wave state,” says Chris Brewer, MA, FAMI, author of Music and Learning (1995).

We couldn’t agree more! In addition to stimulating and motivating, music complements STEM subjects and is great for the STEMists’ souls!

Below are eight music -themed apps that will provide fun learning while motivating your STEMists in their quest for knowledge:

Sound Uncovered – Free by Exploratorium

Sound Uncovered

Sound Uncovered, an interactive book for the iPad, demonstrates the basic principles of sound in an interactive and playful way.  STEMists will discover the world of acoustics, with features of various aspects of sound and music in ‘magazine’ style that make you realize just how much goes into hearing and producing sounds. Sound Uncovered teaches you all about the space between your ears and how our brain deciphers sound.  The app is a must-have for any age to experience fun auditory illusions, unique voice recordings and the creation of sound waves.

Music Theory – Free by Bold Learning Solutions, Inc.

Music Theory by Brandscape

This app offers an excellent review of music theory with flashcards to help STEMists focus on studying large amounts of information.  The app features music symbols and key signatures to composer trivia. STEMists can design their own flashcards where progress is recorded, stored and listed with each round of note cards they review. Plus, you can create flashcards in any study subject organized in the fashion you choose and tailored to a specific test. STEMists will truly excel in their studies with this app. Compatible with iPhone, iPad, and iPod touch. 

Pickup Tunes – Free by RunFly Studios, LLC

Pickup Tunes

Many STEMists can play a song just by hearing it, whereas others need to read the music notes, or practice over and over again to develop the right sound.  Pickup Tunes is an app that will engage STEMists as they learn sound patterns in association to the music notes that represent that pattern.  STEMists will learn to recognize notes by repeating their sounds in this interactive game.  They will progress to various levels as their skills increase, and the program automatically saves your scores and progress.  Compatible with iPhone, iPad, and iPod touch.

Note: The free version provides an introduction to the app, but the paid version ($4.99) will be needed to continue to progress.

Kids Ear Training – Free by Ariel Ramos

Recommended for the younger crowd (children 9-11 years old,) Kids Ear Training is best suited for STEMists who have received prior musical education. The app features two learning modes with many levels that increase in difficulty as you progress and offers some customization features. STEMists will learn instrument families such as brass, woodwinds and strings, in addition to gaining a better understanding of sound concepts such as pitch and intervals.  Compatible for iPad.

Note: Kids Ear Training is safe for all ages; it does not contain social media or external links, ads or in-app purchases.
