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.

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

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

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.

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.

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.

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

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size.

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

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

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

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.
