In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

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

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

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.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

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 a simple air pressure launcher for paper rockets.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

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

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity (located on page 6 of PDF), learners observe and reproduce the distinctive physical features (i.e. plates, sharp spikes, long necks, deep jaws, claws) of their favorite dinosaurs.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

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

In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
