Spring...

...is here. We started our new unit on Planet Earth. Today we learned about the earth's layers. The earth has four layers:

1. The Crust which is 5-25 miles thick.
2. The Mantle which is 1800 miles thick.
3. The Outer Core which is 1400 miles thick (and is liquid)
4. The Inner Core which is 800 miles thick (bigger than then moon).

It is kind of looks like a peach cut in half :)

We also went outside to draw pictures of the first signs of spring (I will post them later) BUT all C. and M. could think about is that it MUST be warm enough to get out the pool and go for a swim... :)
