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

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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

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.

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

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 outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

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.

Learners make a refrigerator that works without electricity. The pot-in-pot refrigerator works by evaporation: a layer of sand is placed between two terra cotta pots and thoroughly soaked with water.

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

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

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

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

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