In this activity students will make observations about the objects, size, distance, and motion of the Sun, Earth, and Moon during a solar eclipse and manipulate slides to show the relationships.

This interactive takes students through the basic mechanics of a solar eclipse, using a NASA Space Place Handout, including an optional eclipse art activity.

In this activity students will calculate the ratio of the size of the sun to the moon and the distance of the sun and moon from Earth to determine the type of solar eclipse possible.

Compare pictures of different volcanoes. Then visit NASA's Space Place to learn about volcanoes and answer questions about volcanic eruptions.

Watch NASA videos about aerosols and volcanic ash.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

In this interactive, students will explore safe methods for viewing the Sun at home or in the classroom, including using solar eclipse glasses and a pinhole projector. The interactive includes a video that explains how the projector works and how to build one.

The Solar Eclipse Implementation Sequence provides a series of lesson plans for students to learn about solar eclipses.

In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).

In this activity students will examine NASA data to determine the differences between a solar and lunar eclipse.
