Frozen Sculptures
Source Institutions
In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

Anti-Gravity Cups
Source Institutions
In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

Ice Fishing
Source Institutions
In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

Tie Dye Secret Messages
Source Institutions
In this activity, learners will write a secret message that only their friends will be able to read.

Divers
Source Institutions
Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

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.

Snow Day!
Source Institutions
In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

Solving Dissolving
Source Institutions
The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

Glow in the Dark Jello
Source Institutions
In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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.

Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.

Building Molecules
Source Institutions
This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

Acid Rain Eats Stone!
Source Institutions
This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
