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

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.

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

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

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 create a hearing based memory game that they can share with friends.

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.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this online activity, learners test their ability to hear different frequencies and compare their frequency range with the frequency range of other animals and insects.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.
