Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

On Target
Source Institutions
In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Fantastic Four: A Math Card Game
Source Institutions
This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.

Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.

Polar Bear Glove
Source Institutions
In this activity, learners will explore how animal in cold areas stay warm.

See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

Designer Seeds
Source Institutions
In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

Toothpick Patterns
Source Institutions
In this hands-on activity, learners use toothpicks to build different triangles and squares and then use the toothpicks to build and solve some tricky shape puzzles.

Rubber Band Car
Source Institutions
In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

Solubility Test
Source Institutions
In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

Butter Up
Source Institutions
In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.

Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Orange Pop
Source Institutions
In this activity, learners surprisingly pop balloons without touching them using orange peels. This Mr.

Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

Bouncing Balloons
Source Institutions
