In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

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

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.

Sound can travel through a variety of media.

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

Put a string around your head, and play it! Learn about vibration, sounds, and pitch.

In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

In this activity, you'll use a paper cup, a piece of cloth, and some string to make a musical instrument called a cuica (pronounced KWEE-kah).
