Reflection

The main purpose of this study unit is to be able to discuss the origin of the universe.

Explain the Earth's place in the solar system.  Also discuss the movement of the Earth and planets within their set orbits by means of a diagram.

We learned the characteristics of 8 planets and the description of laws of planetary movements.

I think what is relevant in this study unit are the YouTube videos because they provide a lot of clarity.

I enjoy Johannes Kepler's laws of planetary motion, most especially the first law which is the law of ellipse.

I think there is anything difficult in this study unit.
