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

This activity offers learners and their families several ways to raise their awareness together about home water.

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 activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners build water-propelled engines from soft drink cans.

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

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

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 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.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
