Earth Size
This is not geography class nor natural science class, but this is only earth pictures, comparing with other planets on the universe. I found this earth image on this sites. Here we go the picture (sorry, I can’t post all picture here, it is too large), I hope this picture useful enough if your kids asking “How Big Our Earth, Daddy?”.
Frankly, I don’t quite sure with terms used in picture 4th and 5th, is it our universe names? I would be very happy if anyone of you can give me a short description about those terms.
