In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

Millions of organisms can live in and around a body of water.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

In this activity, learners use a simple 3D model to discover why the Moon has phases.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

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, two groups of learners create two separate landform models out of clay (mountains and valleys).

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

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

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

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.
