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

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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.

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

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.

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

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

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
