This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

Many people get water from a source deep underground, called groundwater.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this activity, learners make scale models of the Sun and Earth out of paper mache.

This lesson familiarizes learners with the term "tropical belt." First, learners locate the equator, Tropic of Cancer and Tropic of Capricorn on a map and trace these lines with a crayon.

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

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

"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.

In this geology activity, learners use a microscope to discover and identify the components of sand.

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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

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.

“Exploring Earth: Bear’s Shadow” is a hands-on activity designed primarily for young visitors and their families. Participants move a flashlight around an object to make and experiment with shadows.

Exploring the Solar System: Solar Eclipse” is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse.
