Defining Dissolving
Source Institutions
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

Train Your Brain
Source Institutions
In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

Balloon Flinker
Source Institutions
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

Slide Rules
Source Institutions
Learners make their own simple slide rules out of paper and learn how they work.

Dance Diagram
Source Institutions
Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.

Outrageous Ooze: Is It a Liquid or a Solid?
Source Institutions
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

Tri, Tri Again
Source Institutions
Learners estimate how many small triangles will fill a larger shape. Then they use a triangle stamp (or stencil made from a file folder) to fill the larger shape with triangles.

Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.

COSI Quicksand
Source Institutions
In this chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?
Pom-Pom Probability
Source Institutions
In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.

Size and Distance
Source Institutions
In this activity about depth perception, learners create an optical illusion in a shoe box.

Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.

Don't Be Nerve-ous
Source Institutions
In this activity, learners discover a brain process called habituation.

Applesauce
Source Institutions
In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

Race Around the Black Hole
Source Institutions
In this game, learners cutout a model black hole "cone" and attempt to roll around a marble or other small spherical object without touching the event horizon.

Using Tools and Melting Ice
Source Institutions
In this activity, learners will experiment with different materials that can melt and change ice.

Chemistry Is Colorful
Source Institutions
In "Chemistry is Colorful" learners explore different materials through paper chromatography.

Right Eye/Left Eye
Source Institutions
In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.
