The Science of Sound

Ever wondered what makes things buzz, whistle, ring, and sing? Listen up! This box is all about the physics of sound! Inside, steminists will find all the supplies needed to create vibrations, spinning whizzers, and buzzing balloons. Steminists will have a chance to put what they've learned to the test by creating their own boomboxes and quantifying their ability to amplify sound!

Research Sound on the Web!

  • Echolocation

    In this month's box, a lot of the sound waves we work with operate within a range of frequencies that are audible to humans. But have you ever wondered how other animals use sound? Enter: echolocation! Animals like dolphins and bats use sound in this very unique way. The Smithsonian has an interesting video that quickly explains the basics of echolocation.
    Watch echolocation in slow motion!

    Contact

    Back in the 90's one of Kina's favorite scientists, Carl Sagan, wrote a book called Contact about a woman named Ellie, who contacts an extraterrestial race. Her whole life is spent listening to radio waves from deep space, until one day she hears something that changes everything humanity knows. This is a great film to inspire you to reach for the "impossible" and that hard work pays off to those who it matters most. Bonus! It's rated PG.
    Even the trailer gives us goosebumps!

    Very Large Array

    If you've seen the movie Contact or plan on watching it, you'll notice that Ellie spends a large portion of her research career working in New Mexico with a field of satellites. This is what is known as the Very Large Array, VLA for short. Sometimes scientists are boring when they decide to name things. The VLA exists to listen to radio waves from space and have been listening for a relatively short amount of time, so there's a good chance that they'll pick up on something one day. Crazy right?

  • Vocal Fry

    Okay, we have to mention vocal fry, if only to debunk the negative stigma surrounding it. Vocal fry is the deep and scratcy pitched sound made at the end of a sentence. It is alleged that mainly English speaking women use it in speech. It was once considered a speech disorder, but more recent findings are showing it to be more of a style. Some studies have been conducted surrounding the speech pattern. It's a very interesting concept!

Troubleshooting the
Sound Box

There are two ways to fix this problem. With help from an adult, the bonded end of one slinky can be cut using pliers and inserted into the bottom of the cup. Alternatively duct tape to keep the slinky bound to your cup is a good quick fix!

This is a step in the protocol where we insist that an adult complete the step. Box cutters or a sharp knife should be used to cut the rolls in fashion similar to carving a pumpkin.

For android devices we recommend Sound Meter.
For apple phones we recommend Decibel 10.
