In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

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 observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

“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.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

“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 create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, young learners will learn about moon phases using materials found at home. This activity is adapted using play dough and cups to avoid food allergens and waste.

In this activity, learners construct a simple air pressure launcher for paper rockets.
