Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

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 see how many coins they can add to a full glass of water before the water overflows.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this activity, learners experiment with how dish soap and fat interact by making a colorful swirl.

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

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

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 activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

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 chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

Learners identify an unknown liquid by comparing its behavior to known liquids. Learners drop liquids onto different surfaces and see how the liquids behave.

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

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

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.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon
