This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

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 design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

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.

In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

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 (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological even

In this "gross" activity (on pages 34-46), learners make a life-size model of a human digestive tract, and follow the life of a beef tapeworm as it makes its way through.

In this activity (on pages 29-35), learners examine water pollution and filtration.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

Our bodies defend themselves in many different ways to prevent us from getting sick.

En esta actividad, Mateo y Cientina enseñan a usar modelos para ver las causas de las fases lunares.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.
