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.

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

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

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.

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

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this activity, learners construct a device that allows them to look over ledges or around corners.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
