Summary
There are two types of layers for the earth, composition layers and physical layers. There are 3 layers in the earth that we stand on, if you want to get more specific then 5 layers. The inner and outer core of our earth is mostly made of liquid metals like iron, nickel, etc. The pressure in the inner core is so powerful that the liquid forms a solid ball in the earth. Finally the mantle is the largest layer on earth, while the crust is the thinnest, and core is in the middle.

SP2: Developing and using models

This week I made a volcano model out of a special type of glue and newspapers. This is Developing and using models because I started on a volcano model. I also made a rock cycle cartoon. This is developing and using models because it explains about the rock cycle and it's behavior.
