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

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

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 activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners will first learn the basics of galaxy classification and grouping.

“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.

A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners will discover how our universe is continuously expanding.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

“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.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
