Mars from Above: Carving Channels
Source Institutions
In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

Clues About Clouds
Source Institutions
In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

Sound Dampeners
Source Institutions
In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

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

Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

Rock Candy
Source Institutions
In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

Crystals: Grow Your Own Garden
Source Institutions
In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Scream for Ice Cream
Source Institutions
Don't scream for ice cream -- make it with milk, sugar, flavoring and some 'salt-water' ice. Discover the chemistry of ice cream by creating your own.
Become a Master of Inertia
Source Institutions
In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

Crystal Painting
Source Institutions
In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Balloon in a Flask
Source Institutions
Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

Balloon Inside a Bottle
Source Institutions
In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

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.

Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

Frog Eggs
Source Institutions
In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.
