In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

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 quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this activity, learners will explore what a constellation is and make their own.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

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
