This poster shows the path of the moon’s umbral shadow – in which the sun will be completely obscured by the moon – during the total solar eclipse of Aug. 21, 2017, as well as the fraction of the sun’s area covered by the moon outside the... (View More) path of totality. The lunar shadow enters the United States near Lincoln City, Oregon, at 9:05 a.m. PDT. Totality begins in the United States in Lincoln City, Oregon, at 10:16 a.m. PDT. The total eclipse will end in Charleston, South Carolina, at 2:48 p.m. EDT. The lunar shadow leaves the United States at 4:09 p.m. EDT. A partial eclipse will be visible throughout the United States.

This 8.5”x11” brochure has a star chart on the front and a composite image of the sun on the back. The brochure identifies things you may see during totality such as bright stars and planets and key features in the sun’s corona. Users can tear...

This 8.5”x11” bulletin provides a guide to safely viewing the 2017 total solar eclipse on one side and links to more safety tips on the other, including how to prepare for extreme heat, camping and transportation.
Learners will explore aspects of the Sun and solar activity by modeling them as solar cupcakes. Information and imagery are supplied to learn about the Sun, solar activity, eclipses, transits, observing the Sun, and the color of the Sun at different... (View More) times of the day. Links to resources are also provided that highlight NASA's solar missions and where to learn more about the Sun. (View Less)
This video shows the UV Index or strength of ultraviolet radiation received at the surface of the Earth during each month of the year. The UV Index varies with seasons, the sun's angle, clouds, air pollution and land elevation. ClimateBits videos...

This article explains the role of the tilt of Earth's axis on seasonal changes. An accompanying exploration dispels the commonly held misconception that distances between the sun and Earth are a factor. The article is targeted to children ages 10-12.
This is a set of instructions for building a physical model. The model simulates the Sun's paths across the sky at summer solstice, winter solstice, and the spring and fall equinoxes. A bead simulates the Sun, moving along a cord, from rising along... (View More) the eastern horizon to setting on the western. The bead can be moved from path to path to demonstrate solar alignments, the solstices, and equinoxes. The model is created to be unique to the user's latitude, and is useful for including in lessons that teach about the seasons or archaeoastronomy. (View Less)
