Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Indicating Electrolysis
Source Institutions
Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

Candy Chromatography
Source Institutions
Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

DIY Elephant Toothpaste
Source Institutions
In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.

Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

Buoyant Bubbles
Source Institutions
What keeps bubbles and other things, like airplanes, floating or flying in the air?

Indicator Paper
Source Institutions
Use grape juice, baking soda, water and vinegar to make acid and base indicator paper! This activity contains a recipe and instructions for the indicator paper.

Horse Gaits Flipbooks
Source Institutions
In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

Color Me Blue
Source Institutions
In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

Work Up An Appetite
Source Institutions
In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.

Penny Drop
Source Institutions
In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Kool Colors
Source Institutions
Learn about dyes and mordants (fixatives) when you tie-dye fabric with Kool-Aid™ and vinegar. The colored molecules in Kool-Aid™ form a chemical bond between the fiber and dye molecules.

Piles of Pennies
Source Institutions
In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each.

Are We Almost There?
Source Institutions
In this mathematics activity, learners use a map to determine the coordinates of and distance between two locations--both by road and "as the crow flies".

Cold Metal
Source Institutions
In this activity, learners discover that our hands are not reliable thermometers.

¡Ventanas de Burbujas!
