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

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?

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.

Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

Hot and Cold
Source Institutions
In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

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.

Shake the Bag Ice Cream
Source Institutions
In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.
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.

Ice Balloons
Source Institutions
In this activity, learners will explore globes of frozen water to learn how to ask and then answer 'investigable' questions. The activity web page includes a short video demonstration.

Jem's Pykrete Challenge
Source Institutions
In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Instant Ice Cream with a Dry Ice Bath
Source Institutions
In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.
