Summary
Solstice and equinoxes happen every year while Earth revolves around the sun, on it's way for a revolution. Solstice and Equinoxes are in-fact the beginning of new seasons. Tilt of the Earth makes the seasons possible. Summer solstice is the first day of summer and the longest period of sunlight, it occurs in 21-22 june. Fall equinox occurs in September 22-23. It is the first day of season fall and 12 hours day and 12 hours night. Winter Solstice is the first day season Winter and the shortest period of sunlight, it occurs in December 21-22. Spring Equinox is the first day of season winter, equal day and night time. It occurs in March 21-22.
Critical Thinking Question: How is Earth affected by movement (revolution)?
Movements of Earth and Moon affects Earth in various ways. For example, moon phases/lunar revolution causes the water level on Earth to go up and down, which we call "Tide". We get high and low tides everyday and that's all because of the movement of the Moon. Sometimes we see spring tide, in which the water level on earth reaches it's highest and the lowest state in different places. Then we may see some Neap Tide, which is low tide everywhere on Earth. The movement of the Earth causes day and night, when earth spins on it's axis. But when the Earth revolves around the sun, we see solstices and equinoxes or the beginning of different seasons such as summer, winter, spring, fall e.t.c. When the Earth completes it's journey around the sun once in 365 days, we celebrate new year.
Reflection
1. What did you enjoy most about this project and why?
I enjoyed video editing the most. Because I like to work with Imovie.
2. What was most challenging for you during this project and why?
Finishing the movie on time was the most challenging part for me. Because, one of my group-mate was absent for the whole time.
3. What new skills did you learn fro doing this project?
I learned how to work with Imovie. I didn't expect Imovie to be a easy software to edit daily videos.
4. Is there anything that you could have done to improve any of your work? Explain.
If I could, I would've changed the audio of my movie. Because I think it sounds really low at the beginning of the movie but then it gets really loud over time. That annoys me! If I had time, I would've tried to make the audio better. Perfect if I wanted.
