In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

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

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 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 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.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
