Critical Thinking Question

The movement of the earth around the sun in its orbit is called revolution. This movement of the earth is also from west to east. The period of revolution is one year. The orbit of the earth around the sun is elliptical and not circular. Because of this distance between the earth and the sun keeps changing. When this distance is minimum the earth is  to be in perihelion and when the distance is the maximum, the earth is  to be in aphelion. The average of the maximum and minimum distances is called the mean distance and this distance of the sun from the earth is 150 million kilometers.

Reflection

     I liked this project becuase I had fun creating it with the help of my mates. It was fun for me to create this video and the things that were needed to create it. The most challenging for me during this project was to create the video becuase it took a lot of effort and work to complete it. The new skills I learn from this project was to create a video and how the sun and earth work together. No there isn't anything that I could have done to improve any of my work because it my opinion its perfect.
