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

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

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 demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

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.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

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.

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

Millions of organisms can live in and around a body of water.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
