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

In this creativity-based activity, learners imagine what the Earth will look like in the near and distant future, then design their own future habitat and creatures that may live there.

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 investigate the Earth's rotation and how to tell the time of day without a clock. Thsi simple activity only requires a paper plate, a pencil, and sunshine.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

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

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

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

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

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
