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.

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

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.

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.

In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

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

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.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

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

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

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.

Do you have an extra portable cassette tape player hanging around?
