This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

In this activity related to music and sound vibrations, learners make a phonograph or record player out of simple materials. First, learners assemble the turntable, arm, and sound cone.

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

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

In this activity, learners explore how musical instruments are engineered.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

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.

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.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this activity, learners create a straw oboe to explore sound and pitch.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

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.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
