The Amazing Water Trick
Source Institutions
Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

Glow Fast, Glow Slow: Alter the Rate of a Reaction!
Source Institutions
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.

Cool Trees
Source Institutions
This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

Supercooled Water Drops
Source Institutions
In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

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

Make a Water Cycle Wristband
Source Institutions
In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

Water Cycle in a Bag
Source Institutions
In this activity, learners will explore the water cycle by creating a small atmosphere.

Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.

The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

What's in the Water
Source Institutions
"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.

Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

From Gas to Liquid to Solid
Source Institutions
What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.

Atmospheric Collisions
Source Institutions
In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.
