In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this water activity, learners discover ways to move water across the water table.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

Learners act as engineers and design mini submarines that move in the water like real submarines.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

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 (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
