Simple webquest using kidsgeo.com to go through the different layers of the earth, the composition, and depths of each layer.
Using BBC.com students will use the simulation "journey to the center of the earth" to take a trip to the center of the earth they will document what they find at various levels.
Finally they are to label a diagram of the earth with crust, mantle, outer, and inner core.
Worked well with my 6th grade classes.
