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

“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 about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

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 activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this astronomy activity (page 6 of the PDF), learners will compare and contrast two planets in the solar system using data obtained from the internet.

In this astronomy activity, learners create a model of the solar system using beads and string.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through
