4th grader needs to make a model of earths layers showing crust, mantle, and core. Any ideas? Where would I find a picture?
Check this site.
You could make a ball of homemade clay and cut a wedge out to show the layers. Check some of these websites for homemade clay.
type in to google images earth's crust layer and core, then go to the 4th image.
