31. What is the shape of Earth?
Well, it isn’t flat but its also not a perfect circle.
Because of what is called centrifugal force, the earth takes on more of an oval shape.
The earth is spinning so fast and is attracted by the sun that it revolves around, it is constantly being stretched outwards at the equator.
How tall is Earth?
How wide is Earth?

32. Time to practice!
We will be doing stations a little different this time. Today we only have 3 stations and you will be rotating from the front of your row directly to the back
You will each recieve a sheet of blank paper and you are to fold it into 3 equal parts. Number each part Station 1, Station 2, and Station 3 and draw a line to seperate each section
You will have 4 minutes at each station so work quickly!!!
Follow the instructions at each station!
