On August 21, 2017, Oregon will be the first to see the total eclipse of the Sun. This much anticipated solar eclipse will be visible across much of the United States. I first learned of this rare occurrence a year ago and quickly made plans to be sure we would be in the path.
We purchased tickets to attend OMSI’s Eclipse Party at the Salem Fairgrounds and attempted to make hotel reservations in the area to no avail. We have thereby fallen back on a backup plan – staying with family in Eugene and driving up. I fear, however, that the road will be so congested we won’t reach our destination.
Anticipating the 2017 solar eclipse, I am delighted to share with you a number of lessons and activities with which you can engage your middle school students.
About the Solar Eclipse
A total solar eclipse is when the moon moves right in front of the sun, covering it completely for a very short time. It darkens the whole sky, lets you look right at the sun, and shows you the beautiful corona that surrounds the sun. Stars come out, the horizon glows with a 360-degree sunset, the temperature drops, and day turns into night.
Only look at the sun when it is 100% covered. You must use special solar viewing glasses whenever the sun isn’t completely eclipsed or it may cause irreparable eye damage.
The umbra (fully shaded inner region of a shadow) will hit the shores of Oregon at 10:15:53 am PDT near the small town of Otter Rock. From the time the shadow first touches land, it will take only two minutes for the shadow to race eastward. As the eclipse passes over the state, cities will experience various lengths of totality based on their varying distances from the centerline. At the Oregon State Fairgrounds, we will be treated to one minute and 53 seconds of shadow at just after 10:17am.
The eclipse will continue across the United States where Illinois will experience the longest eclipse duration at two minutes and 41 seconds. South Carolina will be the last state to witness the eclipse and the final shadow will be over the Atlantic Ocean near the west coast of Africa. See a map of the full eclipse path.

Past Eclipse Experiences
We have been fortunate to observe an eclipse in the past. In 2012, we enjoyed an eclipse near Red Bluff, California. 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. The characteristic ring of fire. The ring of fire marks the maximum stage of an annular solar eclipse.
There won’t be another total solar eclipse over the United States until 2024. After that, you must wait until 2045.
