Students use simple materials to model a partial, annular, and total solar eclipse.

In this illustrated problem set, students use pi to calculate the size of a Mars rock sample, compare the mirrors of two space telescopes, deduce an asteroid's makeup, and size up a solar eclipse.

In this illustrated math problem, students use pi to figure out how much of the Sun’s disk will be covered by the Moon during an eclipse and whether it’s a total or annular eclipse.

In this lesson, students use their knowledge of moon phases to build a calendar they can use to find out when and where to see each phase of the Moon throughout the year. Calendar for 2023 now available for download!

Students use the Danjon Scale of Lunar Eclipse Brightness to illustrate the range of colors and brightness the Moon can take on during a total lunar eclipse.

Students use a paper plate to make a model that explains why lunar eclipses don’t occur during every full moon.

Students use math concepts related to transits to discover real-world data about Mercury, Venus and planets outside our solar system.

Students use mobile devices to measure the impact a solar eclipse has on the energy received at Earth’s surface.

Students learn about the phases of the moon by acting them out.
