In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).
In this lesson students will calculate the size to distance ratio of the Sun and the Moon from Earth to determine how a solar eclipse can occur.
The Solar Eclipse Implementation Sequence provides a series of lesson plans for students to learn about solar eclipses.
