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

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

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

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.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

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.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

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.

With three cans and some tape, make a drum that you bonk down on any surface to produce a variety of sounds. This activity also teaches you about pitch, vibration, and frequency.

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.

In this activity, learners use sound to figure out, or infer, the position of objects. Learners create a maze inside a shoebox with blocks of wood.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

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 turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

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