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 compare different methods for observing the Sun’s corona and make predictions about what they will observe during the April 8, 2024 total solar eclipse.

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.

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.
