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

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

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

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

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.

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 on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

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

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

In this water activity, learners explore how water drops behave on different surfaces.

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.
