Critical Thinking Question:
How is earth affected by movement(revolution)?
Earth revolution causes the four season. It is
because the orbit of earth is ellipse. Sometimes it is closer and sometimes it
is further. That is why we have Spring, Summer, Autumn and Winter on earth.
Reflection:
I enjoyed making the movie with my group
mates. It is fun and interesting. I think the most challenging part is to
memorize all the information. I learned how to use the iMovie during this
project. If I could do it one more time, I will add more images to the film
because I think it will be easier to let other people to understand what is my
topic about.
