This resource is a tool that calculates the time and date of the March equinox, the June solstice, the September equinox and the December solstice at any geographic location of your choice.

This resource is an article explaining the fall equinox. This resource allows you to enter any city into the article for a precise date and time of the upcoming equinox.

This resource is an activity in which the student will construct a pinhole projector using a cardboard box.

This resource is an article explaining that there are meteorological and astronomical seasons, both marked by specific weather conditions, temperatures or lengths of the days.

In this activity students create a simple pinhole projector for solar eclipses from two sheets of cardboard, as a way to safely watch a solar eclipse.

This resource is an article explaining that seasons happen because the earth spins around its own axis which is tilted at an angle of about 23.4 degrees. Because of this axil tilt, different parts of the earth point toward or away from the sun at different times of the year.

This resource is an article stating that the magnitude of an eclipse is the fraction of the diameter of the disc of the eclipsed body that is covered by the eclipsing body.

This resource is an article explaining that an eclipse is an astronomical event where one celestial body partially or totally covers another celestial body.

This resource is an article explaining that solar eclipses happen when the moon moves between sun and earth, blocking the sun's rays and casting a shadow on earth.

This resource is an article explaining that a blood moon is sometimes used to describe 4 total lunar eclipses that occur in a row. The term also may have come from the reddish glow the full moon can take on when the earth casts its shadow on it and eclipses it.

This resource is an article describing a micromoon. A micromoon happens when there is a full moon or a new moon at the same time as the moon's approach to its apogee - the point in its orbit farthest away from the Earth.

This resource is an article explaining that a partial lunar eclipse happens when the earth moves between the sun and the moon, but they are not precisely aligned. Only part of the moon's visible surface moves into the earth's shadow.

This resource is an article explaining that partial solar eclipses happen when the moon comes between the sun and the earth but they don't align in a perfectly straight line. Because of this, the moon only partially covers the sun's disc.

This resource is an article explaining that a penumbral lunar eclipse takes place when the moon moves through the faint, outer part of the earth's shadow. This type of eclipse is often mistaken for a normal full moon.

This resource is an article explaining that a Supermoon is a full moon or a new moon at its closest point to earth; also called perigee. A Supermoon looks around 12 - 14% bigger than its counterpart, the micromoon.

This resource is an article explaining that a total lunar eclipse can get a deep red glow and it sometimes called a blood moon. Eclipses of the moon happen when the sun, earth and moon are aligned to form an exact or an almost straight line.

This resource is an article explaining that total solar eclipses occur when the moon comes between the sun and the earth and casts the darkest part of its shadow on earth. The darkest point of the eclipse is almost as dark as night.

This resource is an article explaining that an annular solar eclipse happens when the moon covers the sun's center, leaving the sun's visible outer edges to form a "ring of fire," or annulus around the moon.

This resource is an article explaining that there are two equinoxes every year - in September and March - when the sun shines directly on the equator and the length of day and night is nearly equal.
