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.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

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

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

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.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
