Summary: 

Solstices and equinoxes happen because of revolution. Earth spins on it axis as known rotation. Earth tilted to side for 23.5°. An equator divides Earth into two hemispheres: Northern and Southern. There is two solstices: Summer and Winter. Summer solstice happen when earth axis point toward to sun. Direct sunlight comes to northern hemisphere and on the Earth in North Pole are summer season on June 20/21. Same time in southern hemisphere weather is winter season. Winter Solstice happen when sunlight comes in little angle, specific they are not straight which called indirect sunlight. Equinoxes are when equal day and night. There is two equinoxes: Autumnal and Vernal. Autumnal equinox is fall season which starts on September 21/22. Vernal equinox is spring season that starts on March 21/22. The shape of Earth orbit is Ellipse. All these changes happen through movement around the Sun.

Critical Thinking Question: 
How is earth affected by movement (revolution)? 


The Earth is affected by movement. This statement proven by revolution. Revolution happens when the Earth goes around the Sun. The way earth goes around the Sun is called orbit. Climate and time change by this movement as known Solstices and Equinoxes. Solstices is when longest or shortest day of the year.  Equinoxes is when equal day and night. Summer solstices happen under direct sunlight when is longest day of a year on June 20/21. Winter solstices happen under indirect sunlight when is shortest day of year on December 21/22. Autumnal (fall) or Vernal (spring) equinoxes happen when earth gets equally sun rays in both hemispheres. All these events cause by earth movement. 


Reflection: 

• What did you enjoy most about this project and why?
  My most enjoyed part of this project is making video. In addition I was movie editor that help me gain knowledge about imovie. Because we cooperated together and tried to make good and well enough. I enjoyed of doing my work at this project. I hope, I did well.
• What was most challenging for you during this project and why?
  Throughout this project I didn't have challenges. Because members of group exactly knew what to do and helped me to make necessary things. Also teacher gave me all required paper and guide that helped me to figure out quickly. Collaboration and communication skills were helpful to finish on time. 
• What new skills did you learn from doing this project?
  I learnt how to work with imovie software and edit movie that has been done by group. The program worked well, editing process was easy but not enough skills, didn't give me chance to make unique well. By learning how to work with this program, I made some changes and some classmates already gave me feedback. Next time I will use learnt skills to make more interesting. 
• Is there anything that you could have done to improve any of your work?
  Yes, there is something that I could have done to improve my video. I looked through my classmates works and I realize about I need to add some thing to make unique. For example add some captions and song during video. Another parts of our group work has been done perfectly. I wouldn't change anything else except this small detail.
