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.

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

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.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

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

In this activity, learners explore how watermills have helped harness energy from water through the ages.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

Learners shred used paper, add water, and blend it into pulp. They then strain and roll the pulp out to make new paper.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?
