The Exploratorium

Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.

Motor Effect
Source Institutions
In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

Up Periscope!
Source Institutions
This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

Bee Hummer
Source Institutions
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.

Reflections
Source Institutions
In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

Uncanny Motion
Source Institutions
In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

Mirror Reversal
Source Institutions
Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

Short Circuit
Source Institutions
In this activity about electricity, learners explore what happens when you blow a fuse.

Glowing Pickle
Source Institutions
In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

"Baseketball": A Physicist Party Trick
Source Institutions
This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.
