Learners explore water's property of cohesion through two investigations.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

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 quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

Learners demonstrate how water can distort, refract and magnify light.

In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this activity, learners use simple materials to create giant bubbles.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

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 on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

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

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.
