In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this physics activity, learners will explore buoyancy.

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 investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

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, learners will explore how density is affected by temperature and how that can create currents.
