In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners examine nanoscale structures of common things.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

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

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners investigate the properties of graphene and graphite.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners use sieves with different-sized holes to sort balls by size.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

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.

"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

“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.

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

“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 activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.
