Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Snake Kite
Source Institutions
In this activity, learners will explore the physics of air by making a snake kite.

Periscope
Source Institutions
In this activity, learners construct a device that allows them to look over ledges or around corners.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

Metallophone
Source Institutions
In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

Katta Villayatu
Source Institutions
In this activity, learners play a game from India similar to Tic-Tac-Toe. Players take turns placing coins on the game board and sliding the coins along the spaces.

Reaction Time
Source Institutions
In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

All About Air
Source Institutions
In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

Fingerprints
Source Institutions
In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.
Build a Bridge
Source Institutions
In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

Stereo Sound
Source Institutions
We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.
Mystery Jars: Make Your Own: Estimating and Counting
Source Institutions
Learners make a counting/estimating jar to exchange with friends or bring home.

Coffee-Can Cuíca
Source Institutions
Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

Coral Polyp
Source Institutions
In this activity, learners will create their own coral polyps - the basis for a coral reef.

Sticky Snot
Source Institutions
In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.
Pocket Change: Math and Coin Toss
Source Institutions
In this activity, learners will play a coin toss game where the highest total wins. Combine coin recognition, addition, and probability with a game learners can play on their own.

Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.
