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.

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

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

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 investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

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

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

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

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

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