We had been planning to be in the path of totality for over a year, purchasing tickets to OMSI’s eclipse party at the state fairgrounds in Salem, Oregon in July of 2016. As the date approached, the media was inundated with warnings about traffic congestion, fuel shortages, and other issues related to the eclipse.

As we prepared for the event and stressed about logistics – wondering if we should change plans and camp in the Cascades [we would need to pick Geneva up on Friday evening after National Youth Leadership Training – (NYLT)], crash at my brother’s in Eugene, or return home and then drive up to Salem the morning of – we spent time learning more about eclipses.

We had previously seen an annular eclipse and the kids were curious how they differed. Best of all, their interest tied into the requirements necessary to earn the coveted BSA Eclipse patch:

  • Boy Scouts: Draw a diagram of the positions of the moon, earth, and sun to show how the solar eclipse occurs.
  • Venturers: Research Sir Arthur Stanley Eddington’s 1919 experiment and discuss how it confirmed Einstein’s theory of general relativity.

We had recently discovered mysimpleshow and it seemed like the perfect tool for this project. We thereby collaborated (learning how to use the program together) on an explainer video for the 2017 Total Solar Eclipse.

As this was our first multimedia presentation with mysimpleshow, we struggled with a few things (I can’t figure out why a few of the images appear in blue hues) but otherwise we LOVE it! We will definitely be using it again – I’ll be posting a complete review in September so check back. 🙂

Experiencing Totality

After learning more about the location of Geneva’s NYLT camp, we opted to return home Friday evening – we didn’t get home until nearly 1 a.m. She needed the time to decompress after camp however, so it was a wise decision.

We decided to drive up Sunday afternoon and thereby made arrangements to pitch our tent in a friend’s backyard (Thank you, Hannah!). Traffic was not bad on the way up and we arrived rested and excited for the next day.

We meandered the vendor booths and enjoyed the speakers in the amphitheater. The best part of the morning was simply catching up with our friends and taking in each moment – Geneva sketching and Jeffrey cubing.

I loved watching the crowd as the moon eclipsed the sun. Taiko drummers beat out a rhythm as totality approached and were silent during the 1 minute 53 seconds of duration. The crowd was awed and everyone mesmerized by the beauty of the natural event.

It was so fun to experience it with a large crowd – to stop even ever so briefly and not worry about politics or personal strife. Though many people began to depart after totality, we opted to stay.

We enjoyed a leisurely lunch at a nearby Chinese restaurant as we contemplated which route to take to return home. As I5 south was already congested with traffic (our GPS map showed it red for the entire length of the state), we chose to drive slightly westward and then proceed south on highway 99 through Monmouth and Corvallis. This turned out to be a wise choice. Though traffic was heavier than usual, we encountered congestion for only a short stretch between Corvallis and Monroe.

It has been several days now since the eclipse and we are still in awe. It was really incredible and we are so thankful we had the opportunity to experience a total solar eclipse in totality. The next eclipse visible in the United States will be 2024. We may consider making plans for this one as well.

 

 



June 27, 2017

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.

Solar Eclipse 2017We 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.

Three Types of Eclipses

Solar eclipses occur during the new moon phase when the Moon moves between the Earth and the Sun and the three celestial bodies form a straight line, Earth-Moon-Sun. There are three kinds of solar eclipses, Annular, Partial, and Total. On even more rare occasions, a hybrid eclipse occurs when there is a combination of two.

Annular Eclipse

An annular eclipse occurs when the Moon covers the Sun’s center, yet the moon’s shadow doesn’t quite reach the Earth. The Sun’s visible outer edges thus form a “ring of fire” or annulus around the Moon. The ring of fire marks the maximum stage of an annular solar eclipse.

We have been fortunate to observe an eclipse in the past. In 2012, we enjoyed an annular eclipse near Red Bluff, California.

Partial Eclipse

A partial eclipse, which are visible to a greater number of people due to its wider path, occurs when the Moon comes between the Sun and the Earth, but they don’t align in a perfectly straight line and thus the Moon only partially covers the Sun’s disc. A Partial Eclipse can be seen on either side of the path of totality where the moon doesn’t completely cover the sun.

Total Eclipse

A total solar eclipse occurs when the Moon comes between the Sun and Earth and completely covers the face of the sun, letting the sun’s magnificent corona burst into view, and casts the darkest part of the shadow (the Umbra) on Earth. In this shadow, the Earth is almost as dark as night.

Check out the 2017 Solar Eclipse explainer video we created with mysimpleshow.

Hybrid Eclipse

A hybrid solar eclipse occurs when the eclipse changes from an annular eclipse to a total eclipse along the path of the moon as it rotates about the Earth.
