Summary:

The earth around the sun call the Revolution and it rotation length take 24 hours than make day and night. In the earth people image a line on the middle of earth call the axis, and when earth are move the axis tilt degrees of 23.5. When the earth moves, the axes always point a star called Polaris. In the middle of earth, the equator to separates half earth and makes south hemisphere and north hemisphere. In Rotation has two evidence to support it. Pendulum is improving earth rotation and Coriolis effect is control the wind and the currents in the ocean.

Critical Thinking Question:

  When earth movement, the moon would around earth. Earth also moves around the sun. The three are connect each other, we use sun and moon to know day and night.Sun and Moon also affect different season and different of tide. Its affect ocean movement than make low tide and high tide.

Reflection:

• 1. What did you enjoy most about this project and why?
     My favorite part is take video, because on before I did not do it, it is my first time, and it has a lot fun with it.
