Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

Mid-Air Maneuver: Skateboard Science
Source Institutions
To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

For the Birds: Environmental Effects on Population
Source Institutions
In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

Paper Folding: Unfurling Geometric Paper Shapes
Source Institutions
Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

Floating Candles
Source Institutions
In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

Make a "Mummy"
Source Institutions
The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

Ziptop Bag Chemistry
Source Institutions
In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

Design a Grabbing Tool
Source Institutions
Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

Speedboat
Source Institutions
In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

Production of Oxygen
Source Institutions
In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

Earthquake Science: Soil Liquefaction
Source Institutions
This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

"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.

Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

Where Was That?
Source Institutions
In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

Night Lights
Source Institutions
In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.
