Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Real Glass Xylophone
Source Institutions
In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.
Double Dutch Distractions
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.
Buzzing Bee
Source Institutions
In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.
Good Vibrations
Source Institutions
In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.
Double Horn
Source Institutions
In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.
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.
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.
Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.
Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.
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.
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.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Rhythm Painting
Source Institutions
In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Kitchen Jamboree
Source Institutions
In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.
