1. Bell work What do you think is happening in space when solar eclipses happen?

2. Eclipses Solar Eclipses

3. Objectives for today 0607.6.7 Describe the causes of lunar and solar eclipses. SPI 0607.6.7 I can explain the difference between a solar and a lunar eclipse.

4. What is an eclipse? The Sun, Earth, and Moon occasionally line up so that we have an eclipse. –T–T–T–These eclipses happen every year –T–T–T–There are two types of eclipses Solar Lunar –T–T–T–To see a solar eclipse, you need to be on a particular part of the Earth –T–T–T–To see a Lunar eclipse, you need to be on the night side of the Earth

5. What is an eclipse? Celestial bodies are always “eclipsing” or moving in front of each other. Eclipses occur at predictable intervals. Other names include: Transits and Occultations.

6. What is a solar eclipse? A solar eclipse is when the moon covers up the sun! This occurs during the day time. The moon moves in front of the sun.

7. Solar Eclipses When the Moon’s shadow covers part of the Earth Only happens at New Moon Three types: Annular, Partial, and Total

8. Objectives for today 0607.6.7 Describe the causes of lunar and solar eclipses. SPI 0607.6.7 I can explain the difference between a solar and a lunar eclipse.

10. Total Eclipse of the Sun

11. Total Solar Eclipse Observers in the “umbra” shadow see a total eclipse (safe to view the Sun); can see the corona Those in “penumbra” see a partial eclipse—not safe to look directly at Sun Only lasts a few minutes Path of Totality about 10,000 miles long, only 100 miles wide

12. Annular Solar Eclipse When the Moon is too far to completely cover the Sun—the umbra doesn’t reach the Earth Sun appears as a donut around the Moon
