An experiment to create a device using cardboard tubes that will separate a mixture of sounds in a background into their different frequencies, from low to high depending on the tube length.
Exploratorium
Exploratorium: Science Snacks: Polarized Sunglasses
An experiment that demonstrates how polarized sunglasses work.
Exploratorium
Exploratorium: Science Snacks: Proprioception
The human body has proprioceptors that send signals to the brain so that we are aware of our body's position and movements. Try these simple experiments to learn about proprioception and about other visual and tactile clues that assist...
Exploratorium
Exploratorium: Science Snacks: Pupil
Try this experiment to see how light affects the size of your pupils.
Exploratorium
Exploratorium: Science Snacks: Radioactive Decay Model
A simple experiment where pennies are thrown, then half are removed, to simulate how radioactive decay works.
Exploratorium
Exploratorium: Science Snacks: Radiohead
Try this experiment to see how sound transmits as vibrations through solid matter. You will use a toothbrush to listen to the radio.
Exploratorium
Exploratorium: Science Snacks: Remote Control Roller
Investigate the forces of electrons and protons in this experiment with electrostatic charges.
Exploratorium
Exploratorium: Science Snacks: Resonant Pendulum
An experiment in resonance that demonstrates how to make a pendulum swing widely by exerting only a small force.
Exploratorium
Exploratorium: Science Snacks: Resonant Rings
An experiment in resonance that demonstrates how the vibrations of an earthquake affect buildings of different sizes and degrees of flexibility.
Exploratorium
Exploratorium: Science Snacks: Resonator
An experiment in resonance that demonstrates how to synchronize an applied force with an object's natural frequency and amplify the resulting motion.
Exploratorium
Exploratorium: Science Snacks: Rotating Light
An experiment where polarized light is shone into a solution of sugared water, causing each of the colors in white light to change direction in varying amounts.
Exploratorium
Exploratorium: Science Snacks: Secret Bells
An experiment demonstrating how sound vibrations transmit through metal.

Exploratorium
Exploratorium: Science Snacks: Short Circuit
Learn how fuses and circuit breakers work to stop the flow of electricity in a circuit so as to prevent fires. This experiment requires caution.
Exploratorium
Exploratorium: Science Snacks: Soap Film Interference Model
In this experiment, students construct models of larger red and smaller blue waves on index cards, and use them to investigate how light behaves when it is reflected off the front and the back of soap film.
Exploratorium
Exploratorium: Science Snacks: Sound Sandwich
Make a simple wind instrument and use it to experiment with pitch.
Exploratorium
Exploratorium: Science Snacks: Stereo Sound
