In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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

In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this physics activity, learners explore how sound is created by vibrations.

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.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity, learners explore the invisible infrared radiation from an electric heater.
