In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.

In this activity, learners explore the process of condensation.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

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 heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

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.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
