Summary:
Lunar revolution can cause of eclipses. When the moon moves around the earth in different positions, its movement causes phase of the moon. Umbra is the darkest part of the shadow, when the moon moves in umbra, it will become total eclipse. Penumbra is the light part of the shadow, when the moon moves in penumbra, it will become partial eclipse. Solar eclipse is when the moon moves between the sun and earth and blocks the sunlight to the earth. It happens in daytime. Lunar eclipse is when the moon moves into earth's shadow. It happens in nighttime. Both solar eclipse and lunar eclipse have total/partial eclipse.

Critical Thinking Question:
How is earth affected by movement(revolution)?
Earth revolution is the earth orbits around the sun. It takes 365 days or 1 year to revolve one time around the sun. It also rotate on its axis for 24 hours in counter-clock wise while it is revolving the sun. Earth is tilted 23.5 degree. Its axis is point to the north star, Polaris. Because the earth rotation so that we have day and night. Earth revolution causes four seasons which are the spring, summer, autumn and winter. And we can see the movement of the stars. Because it is revolve the sun so that the earth receive different sunlight when it is in different position. That is why we have summer/winter solstices and vernal/autumnal equinoxes.
Reflection:
1. What did you enjoy most about this project and why?
I enjoyed working with my group members, learning new things and organizing the props. We helped each other. Sometimes we had argue and sometimes we collaborated well. I liked to see everybody was working on their part.
2. What was most challenging for you during this project and why?
The most challenging for me during this project was when we need to practice and take video. It was hard to keep everything organized while we were taking the video. Even though we already practiced many times, but it still hard to do
3. What new skills did you learn from doing this project?
I learned how to edit the video. Although I was not video editor, but I learned how to make it fancy and more interesting by watching my group member edited it.
4. Is there anything that you could have done to improve any of your work? Explain.
I could have find more props and retake the video. All the stuff were kind of messy in the video, and some props were not in the right position. I think our video could have be more interesting and detailed.
