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 outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

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 activity (on pages 29-35), learners examine water pollution and filtration.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
