A Solar Eclipse’s Appearance is Different When Viewed from Different Locations.
This article was written for a kindergarten teacher in Tulsa, Oklahoma. I used the following website to view the path of the Moon’s shadow across the Sun.
Caution: Do not look directly at the Sun. It can severely damage your eyes and with long exposure to direct sunlight, you can be blinded.
Caution: Read the safety message from NASA about Viewing a Solar Eclipse.
Note: The eclipse being modeled is to occur on August 21, 2017, but the same basic procedure can be used to model any solar or even a lunar eclipse.
Preparing Materials
1. Cut a circle from the center of a piece of construction paper. Any opaque paper will work. Keep both pieces, the paper with the hole as well as the paper circle.
2. Project the image of the paper onto a screen. If you do not have an overhead type projector, lay the paper on a surface where it can be observed.
3. The paper circle will represent the Moon’s shadow. Place the paper circle over the Sun (cut-out section) 
The illustrations show how the Moon’s shadow will move across the Sun as viewed from Tulsa, Oklahoma and nearby communities.
4. If you are not projecting the image, you might secure the paper circle in the correct position so that only a small part of the Sun is blocked. Point out that even though some of the sunlight is blocked and cannot reach the Earth, you may not notice any change. But as more and more of the Sun’s light is blocked, you will know it. The color of things you see will look different. At one point, during a solar eclipse, things might have a yellowish appearance. That is what I experienced during one solar eclipse. Take note of any changes in color.
5. Take note of the time that each illustration represents. Also notice how much of the Sun is covered and how long it took the shadow to move from one position to the next. 
6. In Tulsa, Oklahoma, the maximum coverage of the Sun during the August 21, 2017 Solar Eclipse is shown in the 1:00 PM illustration. This will be the darkest time. UMMM! We know that there are always stars in the sky, but due to the brightness of the Sun’s light, starlight is not visible. So, during a Solar Eclipse, will it get dark enough for the stars to be visible?
CAUTION: DO NOT LOOK DIRECTLY AT THE SUN ON ANY DAY.
You can search the sky for stars, but do not look in the direction of the Sun, which will be in the south to west part of the sky.
7. The time of the maximum coverage is short– The time for totality, which means the sun is 100% covered, is about 2 minutes and 40 seconds.
8. From start to finish, the partial solar eclipse in Tulsa will last about three hours, starting at about 11:40 AM and ending at 2:34 PM.
9. Following maximum coverage, the Moon’s shadow continues to move toward the east, while the Sun’s apparent motion is toward the west. Thus, less and less of the Sun is covered until finally the solar eclipse ends.
10. Below is a video of a total eclipse in 1979. Enjoy!
