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

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

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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 discover how solar energy can be used to heat water.

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

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

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

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.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

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

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

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 hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

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

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

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.
