Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

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.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

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

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

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 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.

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 activity, learners explore the relative sizes and distances of objects in the solar system.

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