The structure of the earth

School has started again. Sammy worked on a project to model the structure of the earth this week. We had to drive to a Walmart in Frisco to buy a styrofoam ball.  They were sold out at our local Walmart. That's what happens when  Now I know that there are four layers: crust, mantle, outer core and inner core.
