Third
graders learned all about the Earth at Randall Elementary School. Mrs. Cahalan’s
class did a two-week long unit about earth materials.
They
learned there are four layers to the Earth. First layer is the crust, which is
the thin layer we walk on. The second layer is the mantle, which is under the
crust. The third layer is the outer core. And the fourth layer is the inner
core.
“Mikey”
from her class told us the core of the earth is between 8,000 and 9,000 degrees
Fahrenheit. Mrs. Cahalan’s class celebrated all the information they learned by
creating their own earth layers.
