Canjo
Source Institutions
In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.
Anti-Sound Spring
Source Institutions
What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.
Sound Representation: Modems Unplugged
Source Institutions
In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.
Metallophone
Source Institutions
In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.
Stereo Sound
Source Institutions
We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.
Drinking Straw Oboe
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t
Make Your Own Rainstick
Source Institutions
In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.
Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.
Wandering Wands
Source Institutions
In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.
Sound Automata
Source Institutions
In this activity, learners build their own sound machines and explore the interplay of motion and sound.
Tube Zither
Source Institutions
In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
Fun with Flatware: Little Experiments to Try at the Dinner Table
Source Institutions
This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.
Sound Mixer: A Multi-track Mixer of Animal Sounds
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
Organ Pipe: Get Bach to the fundamentals
Source Institutions
If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.
Yogurt Cup Speakers
Source Institutions
Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.
Head Harp
Source Institutions
Put a string around your head, and play it! Learn about vibration, sounds, and pitch.
Right Ear/Left Ear
Source Institutions
In this activity (4th on the page), learners conduct a series of tests to find out which of their ears is more dominant.
Catch the (Sound) Wave!
Source Institutions
See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.
A Penny Saved is a Penny Heard
Source Institutions
In this activity (11th activity on the page), learners use pennies to test their hearing acuity.
